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.

The Series PCWS — dubbed the “stick”— is a multi-function assembly that incorporates the features of a pressure regulator, pressure gage, and shut-off valve into a single unit. This construction eliminates the need for multiple joints and pipe sections, reducing installation costs. The all-thermoplastic stick is designed specifically for process cooling water, and can be used in a variety of applications where corrosion is an issue.

DAB Series all-plastic diaphragm valves are rated to 150 psi and provide excellent handling of difficult media, such as corrosive fluids, abrasives and slurries. They are suitable for use in high-purity and sanitary applications. They are available in manual or actuated (pneumatic or electric) models, and have a multi-turn design that enables precise control. Valve bodies are available in 0.5–6.0-in.-dia. Polyvinyl chloride (PVC), 0.5–4.0-in. dia. chlorinated polyvinyl chloride (CPVC), 0.5–10.0-in.-dia. polypropylene (PPL), or 0.5–8.0-in.-dia. polyvinylidene fluoride (PVDF).

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.

MVBB series single block-and-bleed needle valves have a small valve body. They perform calibration operations by providing controlled flow to high-pressure hydraulic and pneumatic systems through both shut-off regulation and diversion. DBB series double blockand-bleed needle valves are made from cold-worked stainless steel or from 17-4-H1075 (which is Type 630 alloy that has been heat-treated at 1,065°F to 1,085°F for 3.75–4.25 h). DBB valves are suitable for pressure monitoring, chemical injection, and drain-line-isolation applications.

Lab-Crest quarter-turn, full-port, glass ball valves are suitable for use in food, pharmaceutical and biotechnology process applications where contamination is a concern. Their wetted parts are constructed from chemically resistant borosilicate glass, alu-mina ceramic, and TFE, ensuring that the valves are effective in high-purity applications, even in environments where chemicals or gases are present. The valves operate at temperatures up to 490_C and pressures up to 100 psi. The carbon steel flanges can be easily mated to glass or metal piping systems.

A-713 angle valves are soft-seated and self-centering. This design permits self-draining, which reduces the amount of trapped product left in the body after the valve is closed. The valves are constructed of corrosion-resistant materials, giving them maximum protection from materials such as wet chlorine. They are equipped with the capability for live-load valve-stem packing that provides constant force on the packing rings. This compensates for the packing wear and thermal expansion and contraction that normally result when flashing occurs in the system.

Valtek ShearStream SB segmented V-port ball control valves have a rugged design that is cost-competitive. They feature standard metal and soft-seat options that provide tight shutoff for ANSI Class 150 and Class 300 service. The direct-mounted actuator allows for better control with fewer parts, and has a double-acting piston and precision linkage connection for accurate control and high-torque output.

The Fast Pack prepackaged combinations of valves and actuators boast an expedited delivery process. The manufacturer guarantees that orders will be sent out within 24 hours of being placed. Packages are available in a range of diameters, including 0.5-in. to 4-in. ball valves and 1.5-in. to 8-in. butterfly valves. Specific pairings and combinations will vary, and include electric ball valve, pneumatic ball valve, electric butterfly valve, and pneumatic butterfly valve packages.

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.
