Directive*Duo-Chek meets or exceed these industry standards.

Dual plate lightweight design for e�cient seating and operation.

Long-leg spring action allows plates to open and

close without seat scrubbing.

Spring action closes plates independently. (6" and larger)

Hinge support sleeve reduces friction and minimizes water hammer through

independent plate suspension (on larger sizes).

Retainerless valves for critical applications without pin retainer penetration through the body are available in Wafer and are

standard in Lug and Double Flange valves.

Retainerless Check Valves

High Performance Check Valve for Critical ApplicationsFor critical applications, retainerless Dual-plate Check valves feature a one-piece body with no pin retainer penetration through the body. These high performance valves utilize the same internal design of other Dual-plate Check valves with all the unique features and advantages built into them.

Because Retainerless Dual-plate Check valves have no body penetrations potential leak paths through the valve are eliminated. This makes the Retainerless Dual-plate Check valves ideally suited to meet the following critical service applications:

• Hydrocarbon processing• Chemical processing• Any industry concerned with fire hazards or environmental

safety.

Key features of the wafer check valve include:• A wide selection of body and plate materials• A choice of metal-to-metal or resilient sealing• A full range of pressure classes and sizes• A variety of end connections• Designs available include wafer, lug and double flange• Internals easily removed for field replacement under normal

inspections and maintenance procedures

The advanced design provides many operational benefits to the user, which combined with its more compact size and lower weight, make an excellent alternative to a standard swing check valve.Remarkable advantages include:

• Independent spring action (on 6” and larger) and plate suspension on larger valves

• Free release flat seats• Springs provide superior response to flow reversal or

deceleration• Minimal water hammer• Savings in purchase price and installation costs compared to

a conventional swing check valve• Single body design with no body cartridge

Spring materials are included in trim materials as an important partof materials selection. The most common standard trim materialsare shown under Ordering Information.For unique service conditions, different torque springs as well asother spring materials are available. Please consult factory.

All drain holes are located on the downstream side of the valve.

•

•

Spring cracking pressure is an estimate of the pressure required to overcome thespring force when valve is closed. This is not exact as valve cannot be used as arelief valve. The use of low and min. torque springs could effect the valve performanceand should only be used when unique service conditions are evaluated.Valves 6" and larger have independent springs.

please consult factory.
