Single Disc Wafer Swing Check Valve

PTFE commercial spacer, ASTM A307B carbon steel plug and eye bolt

Economical design - low weight and short laying length produce savings in initial cost, space requirements and installation when compared to full body, swing type check valves

Minimal head loss - head loss is minimized by providing a short, straight and virtually unobstructed flow path, additionally, the spring loaded disc is designed with very low cracking pressure which reduces the amount of energy required to open the valve

Quick closure to reduce water hammer - shut-off is achieved via the fully automatic, spring assisted disc that closes near zero flow velocity, the lightweight, single disc design creates a positive shut-off prior to flow reversal which helps to keep surges to a minimum

Durable, high quality design - the CV32 check valve is available in either carbon steel or stainless steel body configurations, which allow it to perform well in higher temperature applications, the carbon steel units are epoxy painted, additionally both models feature anti-corrosive, stainless steel trim (disc, spring, shaft) as standard

Resilient soft seats (viton and PTFE o-ring) coupled with precision machined sealing surfaces help to ensure a bubble tight seal that meets or exceeds API 598 test requirements

14 - 248 deg F seat

450 deg F spring

Cracking pressure is for horizontal installations only

Service - intended for liquid service that is steady, clean (no abrasives or solids ) and non-pulsating, flow rate should not exceed 15 fps, not recommended for steam or reciprocating compressor service

PTFE properties - recommended for most chemical environments including acids, bases, oils, steam and other process fluids, offers excellent tear, abrasive, chemical, acid and alkali resistance, not recommended for high pressure steam or large temperature variation application
