this month's topic ValvesHigh-Flow Solenoid Valve is Equipped with Fail-Safe Mechanism
This high-flow direct-mount solenoid valve has a NAMUR mounting pattern and handles flowrates from 1.2 to 3.0 Cv. Its spring return allows fail-safe operation in the event of a power loss, and its screened exhaust nut protects valve function during outdoor use. It operates over a pressure range of 30–150 psi. At the higher pressures, the O-ring seal design increases sealing force, while at the lower pressures, this design provides less breakaway resistance. The valve is constructed of an anodized aluminum body with a stainless steel spool and internal parts are made of brass. It operates at fluid temperatures of 32°F–122°F and can be mounted in any position.

Valve Controller Adjusts for Closed, Fully Open and Intermediate Flows
The AXIOM Expeditor improves process performance and prevents damage to equipment in fill-control, flow-dampening, and thermal-shock-reduction applications. The device allows discrete automated valves to be easily upgraded to provide intermediate control. Its pneumatic solenoid technology requires no special bleed pilots or air filtration systems. The controller’s operation is simplified because its integrated control system permits valve cycling between fully open and fully closed, as well as intermediate control. A standard discrete 24-VDC output is used for the on/off solenoid operation, and a 4–20-mA analog input performs intermediate control. A standard 4–20-mA input circuit monitors valve position.

Swing Check Valve Weighs Less than Competitive Valves
The Noble Alloy swing check valve resists corrosion and performs reliably in severe-service chemical applications. Because the redesigned valve is forged, it weighs 45% less than the previous cast version and provides improved bonnet-seal performance. The valve has a recessed hinge pin that is protected from the flow path, as well as an integral seat design and a high-integrity riveted disc assembly. The valve can be installed horizontally or vertically, and is available with soft or metal seating. It features multiple end connections and bolted-bonnet construction.

Miniature Isolation Valve uses Magnetic Flipper
The Type 6650 3/2 miniature solenoid isolation valve’s patented flipper technology employs an elastomer element that moves between opposite seats under the force of permanent magnets, which are fixed to the flipper element. This configuration opens one flipper as it closes the other, providing a fast response. The valve’s optimized design ensures reproducible and precise dosing and effective rinsing, making it suitable for use with aggressive chemicals. It measures 4.5 mm wide, and outperforms comparable 10-mm and 16-mm designs. The Type 6650 is offered in a 3/2 model and a 2/2 model, both with bodies made from high-performance polyetheretherketone (PEEK) and seals made of perfluoroelastomer (FFKM).

Easy-to-Clean Safety Valve has Secondary Containment
The Clampseal fire-safe valve is equipped with a vent drain instead of the standard bull-plug and screwed-cap designs commonly found on other valves. The vent drain provides secondary containment, as well as pressure-purge, no-spill gravity drainage. The valve contains a simple mechanism that compensates for thermal expansion, and is available in Y, A and T configurations in sizes ranging from 0.5 in. to 4.0 in. The valves are manufactured to meet the ISO 9001-2000 standard.

Solenoid Valve has Power-Loss Fail-Safe Design
The J Series solenoid valve has a pilot-assist design that requires only a 3-psi differential on either side of the valve and that provides high flowrate with minimal pressure loss. To meet the needs of various applications, models are available that fail open or fail closed upon power outage. For example, a valve used on a reactor would be set to fail open to avoid pressure buildup, whereas a valve used in a filling line would fail closed. The valve’s cycle speed is 0.25 ms in either direction. The series is available in a two-way configuration in sizes of 0.375 in. to 2.0 in., with pressure ratings up to 225 psi (150 psi max for steam). Valve bodies are made from brass and have diaphragms made from BUNA (butadiene and sodium) or EPDM. End connections are female NPT (FNPT) with DIN connector coils that have a cord grip. The J Series solenoid valve is suitable for water, gas and steam applications.

Plastic Butterfly Valves have One-Piece Construction
Poolmaster Series butterfly valves feature a polyvinyl chloride (PVC) body and a disc with an ethylene propylene diene monomer (EPDM) liner. The valves are not vulnerable to electrolytic and galvanic corrosion, and they contain no byproducts that can contaminate water and process fluids. Unlike other plastic butterfly valves, these are constructed from a one-piece body that incorporates fully supported flanged bolt holes to prevent stressing of the mating pipe flanges. A blowout-proof Type 316 stainless steel shaft and a full body liner ensure positive sealing of the liner to the valve body. A solid integral ISO 5211 mounting pad enables smooth operation with a lever handle, gear or actuator. Options include gear operators, electric or pneumatic actuators, actuator mounts, and stem extensions. The valves are available in 2.0–8.0 in. sizes.
