It features a large backlit display with a dial-type digital bar graph and separate lines for units and measurements. The transmitter integrates with the PC COMM software for quick device configuration. Panel- and field-mount versions are available, and both configurations run on 12- to 32-VDC power. It is appropriate for use in wastewater treatment, chemical dosing and delivery, metal and plastic finishing, fume scrubbers, cooling towers, and filtration processes.

Type 561 and Type 562 cone check valves
The Type 561 and Type 562 cone check valves have an aerodynamic, spherical-shaped cone that ensures tight closing and leakproof operation. The cone’s double bearing prevents it from tilting, even during rapid closing, and eliminates malfunctions. Other design features include a cone guide that prevents jamming; a fixed gasket that eliminates slipping, bending, or gasket erosion; and a union that allows for easy replacement or maintenance in the field. The Type 562 valve has an integrated stainless steel spring (other material options are available) for horizontal installation, while the Type 561 valve has no spring and is mounted vertically. The valves have an operating pressure rating of 2.9 psi and are available in sizes from 3/8 in. to 4 in. Materials of construction include polyvinylchloride (PVC), chlorinated PVC (CPVC), polypropylene, polyvinylidene fluoride (PVDF), and acrylonitrile butadiene styrene (ABS); sealing materials include ethylene propylene diene monomer (EPDM) rubber and fluoroelastomer (FPM).

Ultrasonic Flow Measurement Devices
This new family of ultrasonic flow-measurement devices includes two portable models (Portaflow 220 and 330) and two fixed-installation models (Ultraflow 3000 and 4000). Both types display instantaneous and totalized fluid flowrate and velocity data, and can be installed quickly without interrupting the process. Data can be downloaded directly to a computer or printer, or stored in the instrument’s memory and downloaded later. The instruments are supplied with two types of transducer sets to accommodate pipe sizes up to 78 in. o.d. The transducers are attached directly to the outside of the pipe being monitored, which allows for complete installation without disruption to the process or equipment. External mounting keeps components from making contact with the fluid being monitored, so there is no risk of either contamination of the process fluid or exposure of the equipment to corrosive or toxic liquids. For this reason, these devices are suitable for high-purity and ultrapure applications.

PE100 Industrial Polyethylene piping
PE100 Industrial Polyethylene piping retains its mechanical strength and high impact resistance at temperatures as low as –58ºF, where other plastic materials typically degrade or suffer degradation of physical properties. Its performance characteristics include light weight, flexibility, compatibility with a broad range of chemicals, and abrasion resistance that allows it to be used with brine solutions, dissolved solids, and slurries. PE100 conforms to ASTM, NSF and FDA standards and is suitable for fluid transport in process cooling water, industrial water treatment, bulk water distribution, and chemical processing applications. Pipe sizes range from 2 in. to 36 in., with molded fittings of 2–12 in. and fabricated fittings of 14–36 in. Valves of compatible sizes, including compact tee, ball, diaphragm, butterfly and check styles, are available. Installation is performed using one of three fusion joining technologies, depending on pipe diameter: infrared butt fusion for sizes 2–8 in., contact butt fusion for sizes 2–36 in., and electrofusion for systems 2–26 in. All three technologies provide simple, safe and secure heat fusion joining and controlled butt fusion and weld traceability

Signet 8550 flowmeter
The Signet 8550 flowmeter converts the signal from a flow sensor to a 4–20-mA signal for long-distance transmission. It features a choice of single or dual input/output, as well as two optional relays for process control, and scalability for almost any flow range or engineering unit. The flow-meter is available in three packaging options: integral/pipe, universal field mount, and panel installation. It has an operating temperature range of–10°C to 70°C (14°F to 158°F), and its National Electrical Manufacturers Association (NEMA) 4X enclosure has a self-healing window.

DoubleSafe fittings
DoubleSafe fittings provide a leakproof seal and prevent cracking under high torque when installed as the transition between metal piping and the manufacturer’s plastic piping. The fittings are pressure-rated to 150 psi and are available in polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC). This metal-to-plastic joining is useful for connecting a plastic piping system to heat exchangers, flowmeters, and other metal-ended, male-threaded instruments. These joints may also be used to expand old metal systems with plastic and to install plastic systems where metal is required for only part of the configuration. Since plastic pipes often split when metal threads are over-tightened into plastic fittings, each DoubleSafe incorporates a female-threaded metal insert molded at high pressure inside a spigot-end plastic body, which allows the installer to connect the metal system to the metal side and the plastic system to the plastic side.

Type 567 and Type 568 butterfly
Type 567 (wafer style) and Type 568 (lug style) butterfly valves are now available with large diameters (2–12 in. for Type 567 and 2–8 in. for Type 568). They feature a disc and liner made of polyvinylidene fluoride (PVDF) and seals made of polytetrafluoroethylene (PTFE) that provide excellent chemical resistance over a wide temperature range. Both valves have an operating temperature range of –20°C to 120°C (–4°F to 248°F), and can be electrically or pneumatically actuated. They also offer bidirectional capability and a high pressure rating of 150 psi. The valves are suitable for use in chemical processing, chlorine electrolysis, chemical production, food and beverage sanitation, pulp and paper, and steel production applications.

Signet 4150 turbidimeter
The Signet 4150 turbidimeter features easy calibration with simple one-unit installation and setup. Its accurate, reliable water-quality monitoring complies with the U.S. EPA 180.1 standard, making it suitable for both municipal and industrial applications. It is available in two models: the 0–100 NTU (nephelometric turbidity units) version, which handles low-range applications such as potable water monitoring, and the 0–1,000 NTU version, which is designed for higher-turbidity applications, including raw water and waste-water monitoring. Turbidity measurement is accomplished through a 90-deg. light that reflects particles as they flow through a cuvette, providing continuous and accurate online measurement. The meter’s replaceable desiccant pack ensures a stable environment for accurate measurement, and its built-in backpressure valve can be adjusted to eliminate bubbles that can cause reading errors. It has a 4–20-mA output signal, two programmable alarm relays, and a bright backlit display.

Calorplast heat exchangers
The Calorplast thermo-plastic all-welded heat exchangers are designed for cooling or heating in highly corrosive applications, including heating of pickling acid solutions, electroplating, anodizing, removing heat from chemical reactions, and acid recovery systems. They can be made of polyvinylidene fluoride (PVDF), polyethylene, or polypropylene, and are available as immersion, shell-and-tube, tube-plate, gas-liquid, and flexible heat exchanger models. Heating media options are saturated steam or hot water up to 35 psig at 281ºF; cooling media options are chilled water or water/glycol solutions. To meet the needs of specific applications, certain performance characteristics can be customized — for example, all-welded construction, low fouling, low pressure drops or enhanced chemical inertness. The exchangers can also be made to eliminate stray currents.

Electro Plus Fusion Machine
The Electro Plus Fusion Machine joins thermoplastic pipes and fittings in corrosion-resistant piping systems used in chemical processing facilities, pharmaceutical waste systems, semiconductor manufacturing, power plants, pulp and paper mills, and corrosive-waste disposal systems. Operated via a hand-held, user-friendly interface, the machine employs electrical resistance heating to join thermoplastic parts together. It can process multiple joints during a fusion cycle, and features a one-button repeat function for same-sized joints. The machine has an operating temperature range of –10ºC to 45ºC and automatically compensates for ambient temperature. Its input voltage requirements are 100–130 VAC or 200–250 VAC 60 Hz. It weighs 45 lb and measures 22-in. wide × 14-in. deep × 10-in. high. Its durable design allows for use in harsh field environments, and a built-in safety feature prevents the fusion cycle from restarting while the machine is connected to the piping.

Type 567 butterfly valve
The Type 567 butterfly valve is now available with a larger diameter in sizes up to 12 in. This corrosion-resistant valve uses a double-eccentric operating principle that offers improved wear and easier operation compared to traditional eccentric-style butterfly valves. This design requires less torque to operate the valve, facilitating manual operation and permitting the use of smaller, less-expensive actuators. Its off-center shaft allows the disc to completely disengage from the disc seal, even while partially open. Typical applications for the valve include water treatment, potable water treatment, and industrial wastewater systems.

SYGEF PVDF (polyvinylidene fluoride) Exhaust Piping System

Outstanding performance characteristics include UV-resistance, a wide operating temperature range from –4 ºF to 284 ºF and a vacuum rating of 0.218 psi, 6-in. water column.

Type 568 lug-style butterfly valve
The Type 568 lug-style butterfly valve has shaft seals that incorporate a double O-ring to protect against external leakage. A disc seal replaces the traditional rubber liner to allow the disc to completely disengage from the seal upon valve opening, reducing friction and improving wear capabilities. The disc seal also incorporates a cross-sectional profile that mechanically retains the seal in the valve body. And a specially engineered body seal features a Q-shaped O-ring that eliminates the need for flat gaskets. The valve has a modular design with an epoxy-coated iron lug body. The wetted inner body, disc and bearings are available in PVC, chlorinated PVC (CPVC), polyvinylidene fluoride (PVDF) or polypropylene (PP) to match the outer pipe material, providing excellent chemical compatibility throughout the system. With a pressure rating of 150 psi, the valve can withstand operating temperatures up to 120°C (PVDF), 80°C (PP and CPVC) or 60°C (PVC). Designed for dead-end service, the valve enables a piping system to be capped off, yet allows future modification or expansion of the pipeline without depressurizing the system.

Schedule 80 polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) piping systems
By expanding its Schedule 80 polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) piping systems to include molded caps in 10- and 12-in. sizes,  this company now offers a  comprehensive range of piping in sizes from 1/4 in. to 16 in.  The product line features molded Flush Style Reducer Bushings through 12 in., as well as fabricated fittings through 16-in. Corrosion resistant, lightweight, and able to withstand temperatures up to 140ºF  and 210ºF (PVC and CPVC, respectively), these molded products are more cost-effective than machined parts, thereby lowering overall installation costs.

Type 567/568 butterfly valve series
Designed for industrial, potable and wastewater treatment systems, the Type 567/568 butterfly valve series features a double-eccentric-disk design typically found only in high-end metallic configurations. This double eccentricity reduces seal friction and wear, resulting in longer service life, minimal maintenance and better protection against pressure surges. It also lowers the torque required to operate the valve, easing manual operation and allowing the use of smaller, less expensive actuators. The 567/568 series feature a modular design ranging in size from 2 in. to 8 in., with either a glass-filled polypropylene wafer body (Type 567), or an epoxy-coated iron lug body (Type 568). The inner body, disks, and bearings are available in PVC, polypropylene and polyvinylidene fluoride. The lockable ergonomic lever enhances worker safety via a 5-deg ratchet setting that ensures precise positioning of the lever and eliminates incidental movement due to accidental bumping of the handle. Other safety features include an integrated electric position indicator in the mounting flange that shows whether the valve is open or closed. An index plate clearly indicates the angle opening in degrees.

Signet 8150 flow totalizer
Long-lasting, standard lithium batteries make the Signet 8150 flow totalizer ideal for remote or mobile installatioins where access to line power is limited. Because of its low-power-consumption design, these batteries are rated to last up to four years (nominal). The unit is offered with three totalizers — two are resettable for long-term and short-term monitoring, and the third is permanent. A large LCD display indicates both flowrate and total flow volume simultaneously. The 8150 is available in both integral and panel-mounted styles, and can be provided with NEMA 4X protection.
