Shut-Off Valves suit liquid service from vacuum to 150 psi.
Fluid & Gas Flow Equipment

Shut-Off Valves suit liquid service from vacuum to 150 psi.

With no wetted metals or external fasteners, Â-½ in. Series BSR is designed for high-purity or corrosive environments. Backpressure can be as high as inlet pressure without affecting performance. Diaphragm style valves use compressed air for operation and will close in event of pressure loss. Valve bodies are unpigmented polypropylene or grade 1, type 1 PVC. Internal metal springs are...

Pump Bypass Valves are corrosion-resistant.
Fluid & Gas Flow Equipment

Pump Bypass Valves are corrosion-resistant.

Available in pipe sizes from Â-¼-3 in., thermoplastic Bypass Relief Valves protect chemical process systems from pump dead-heading by automatically diverting flow through NC bypass line in case of obstruction in piping system. Available body materials include PVC, polypropylene, Corzan CPVC, Kynar PVDF, and PTFE. Featuring flow rates from 2-200 gpm and set pressures from 5-150 psi, valves...

Relief Valve works with lined steel piping.
Fluid & Gas Flow Equipment

Relief Valve works with lined steel piping.

Teflon® Diaphragm Relief Valve features thermoplastic body with intrinsic flange, eliminating piping nipples and other threaded connections. Teflon® diaphragm and plastic body combine to provide non-leaching, contamination-free relief/by-pass valve. Flange connections are available in Teflon® PTFE, Kynar PVDF, and natural, unpigmented polypropylene.

Diaphragm Check Valves are manufactured from Corzan® CPVC.
Fluid & Gas Flow Equipment

Diaphragm Check Valves are manufactured from Corzan® CPVC.

Corzan Series CKM Check Valves prevent unwanted and potentially dangerous reverse flow in piping systems. Diaphragm design provides positive, leak-free seal, even in non-flowing condition. Suited for applications that require elevated temperature- and corrosion-resistance, valves are not dependent on gravity, mounting position, or reverse flow for proper functionality. They are available with...

Check Valves provide bubble-tight seal.
Fluid & Gas Flow Equipment

Check Valves provide bubble-tight seal.

Series CKS consists of self-sealing, thermoplastic check valves for corrosive and ultra-pure liquids. Designed to safeguard process systems, units maintain positive closure even in absence of reverse pressure. Offered in 1Â-½, 2, and 3 in. pipe sizes, valves use spring encapsulated with Teflon® PFA to protect liquids from contamination. Standard body material is Grade 1, Type 1 PVC.

Ball Valves suit corrosive and ultra-purity applications.
Fluid & Gas Flow Equipment

Ball Valves suit corrosive and ultra-purity applications.

True Blue Series ball valves universally accept air or electric actuators, limit stops, and limit switches without need for modification or adaptors. Water and dust-tight actuators are constructed of non-corrosive thermoplastics and feature flow position indicators. Available in pipe sizes Â-½-2 in., valves are offered in 2-way and 3-way configurations with dual-shaft seals,...

Check Valve is not dependent on gravity for sealing.
Fluid & Gas Flow Equipment

Check Valve is not dependent on gravity for sealing.

Able to maintain bubble-tight seal when mounted in any position, valve diaphragm automatically positions itself against valve seat in identical location each time. With no internal sliding or loose parts to slam or vibrate, chattering is eliminated, and operation is silent. Available in Â-½, ¾, and 1 in. NPT sizes, body materials are PVC, Polypropylene, PVDF, and Teflon®....

Ball Valve increases safety in plastic piping systems.
Fluid & Gas Flow Equipment

Ball Valve increases safety in plastic piping systems.

Lateral reducing Series LMBV eliminates vulnerable area between ball valve and tee in piping connections. Adapter connects ball valve directly to piping tee and valve remains fully functional if accidental break occurs in line. Product is available in Geon® PVC, Natural Polypropylene, Corzan® CPVC, and Kynar® PVDF. Lateral tee connections on adapter side range from Â-¾-3...

Thermoplastic Valve suits critical applications.
Fluid & Gas Flow Equipment

Thermoplastic Valve suits critical applications.

Based on globe-style flow pattern with direct operation of valve shaft, air-actuated Series ASO can be operated pneumatically or hydraulically to provide positive, bubble-tight shut-off. Design incorporates clear, acrylic upper housing and heavy-duty spring and is available in 5 types of operation. Valve shaft, machined of solid Teflon®, eliminates sticking, while Fail-Dry® safety...
