Basic-Check® Threaded In-Line Check Valves

Basic-Check® Threaded In-Line Check Valves

(44)
The DFT® Basic-Check® valve is a versatile all-purpose, spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of liquids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, retaining ring and seat. It can be combined with pipe fittings such as reducing couplings, drain elbows, etc. to form a complete check valve unit ideally suited for a broad range of pipeline applications or incorporated into machinery for OEM applications. The metal-to-metal sealing area of the Basic-Check® valve’s disc and seat is precision lapped, providing very tight shut-off of both gas and liquid. If bubble-tight shut-off is required, ...

Restrictor Threaded In-Line Check Valves

Restrictor Threaded In-Line Check Valves

(44)
The DFT® Restrictor Check Valve (RCV) is a versatile, all-purpose, spring-assisted, in-line check valve for applications that require higher cracking pressures to open the check valve than those offered by other DFT® check valves. Cracking pressures are available from 2 to 40 psi. Like the Basic-Check® valve, the Restrictor Check provides reliable, low maintenance service for a wide range of fluids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, retaining ring and seat. It can be combined with pipe fittings such as couplings, drain elbows, etc. (not provided by DFT®) to form a complete check valve unit ideally suited for a broad range of applications. The RCV ...

SCV-R® In-Line Restrictor Check Valves

SCV-R® In-Line Restrictor Check Valves

(103)
The SCV-R® is an in-line spring-assisted check valve designed for applications requiring "higher cracking pressures" than the DFT Model SCV® check valve. The SCV-R® is a self-contained check valve that installs directly in a pipeline and contains all of the proven features of the SCV® check valve.

Vacuum Breaker Threaded In-Line Check Valves

Vacuum Breaker Threaded In-Line Check Valves

(13)
DFT® Vacuum Breakers provide effective protection against collapse of pressure vessels, tanks and rolls. They prevent condensate "back-up" when equipment is shut down or inlet steam is reduced by modulating control valves. In piping systems, DFT® Vacuum Breakers are used to break siphons, prevent pipe collapse during transient pressure drops, and to provide addition of air on the downstream side of check valves to dampen water hammer.
