“Econostyle” Check Valve

The patented “Econo Check” check valve is designed for non-oil lubricated compressors for 5 HP and under.  The compact valve design has proven to be a robust economical check valve that has sold over 8 million units in the past 10 years.

Construction: One-piece brass or plated steel body with a stainless steel spring, Fluorocarbon poppet  and high temperature engineered thermoplastic internal guides.

Max. Pressure: 200 psi
Max. Temperature: 400ºF

Piston-Type Check Valves

Our Piston-Type Check Valves offer bubble-tight sealing capabilities at low pressure drops. Uses include as tank check valve for small compressors or as components in pneumatic circuits.

Construction: Brass body and pistons, fluorocarbon O-rings and stainless steel springs
Max. Pressure: 250 psi
Max. Temperature: 250ºF

“B2” Check Valves

The “B2” check valve design has been specifically developed for OEM use, offering outstanding performance. High flows are ensured with oversized discharge holes and final assembly is a swaging operation, which provides the valve with a long life, but does not allow for disassembly. The “barrel” length of the “B2” check valve is shorter than the Super-Chek line, so the OEM must ensure that any “skirt” on the tank is clear of the valve discharge holes, otherwise potentially damaging back-pressure may build up on the compressor discharge line and compressor head.

Construction: Brass body, stainless steel springs and glass-filled PTFE poppet
Max. Pressure: 450 psi
Max. Temperature: 400ºF

Super-Chek Check Valves

The Super-Chek design has been proven over the last 15 years to be the standard for air compressor in-tank check valves. Valves may be disassembled for cleaning or repair and are 100% tested for backflow leakage performance.

Construction: One-piece brass body with stainless steel springs and glass-filled PTFE poppets with eight (8) discharge holes for quiet operation
Max. Pressure: 450 psi
Max. Temperature: 400ºF

Cast Brass (“CB”) Check Valves

The cast brass check valves have been specifically designed for installation into air compressor discharge lines. These valves come standard with a plugged 1/8” NPT unloader port.

Construction: Extra-heavy duty brass body, glass-filled PTFE poppets and stainless steel springs
Max. Pressure: 250 psi
Max. Temperature: 450ºF

Bar Stock Poppet-Type (“IC”) Check Valves

Our “IC” in-line check valves were created around our Super-Chek design. An “IC” valve can be installed in the discharge line of the compressor in those instances where an in-tank valve will not fit. These valves come standard with a 1/8” NPT un-loader port.

Construction: Brass body, glass-filled PTFE poppets and stainless steel springs
Max. Pressure: 450 psi
Max. Temperature: 400ºF

Ball Check Valves

Our ball-type check valves offer bubble-tight sealing capabilities at low pressure drops. Uses include as tank check valves for small compressors, or as components in pneumatic circuits.

Construction: Valve bodies are brass with fluorocarbon O-rings, stainless steel balls, stainless steel springs and acetal copolymer “cages”.
Max. Pressure: 250 psi
Max. Temperature: 250ºF
Options: Model “C5038” available with adapter for 1/4” OD copper tubing compression fitting for compressor unloader application
