GLC® Flanged Check Valves

GLC® Flanged Check Valves

The DFT® Model GLC® Silent Check Valve is a spring-assisted, center guided, in-line, flanged check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. The valve consists of a body, seat, spring, disc with stem and guide bushing. Some valves have body or gasket seals. The DFT® GLC® check valve has the advantage of minimum pressure loss with silent, non-slam operation.

PDC® Flanged Check Valves

PDC® Flanged Check Valves

The DFT® Model PDC® Silent Check Valve is specially designed for use on the discharge side of reciprocating air or gas compressors. It includes a pulse damping chamber to maintain the disc in the open position during the momentary reductions in flow associated with each cycle of a reciprocating compressor and to protect against premature seat wear.

Excalibur® Flanged Check Valves

Excalibur® Flanged Check Valves

The DFT® Excalibur® Silent Check Valve is a spring-assisted, center guided, in-line, check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations. The valve consists of a body, gasket, seat, spring, disc with stem and guide bushing. Excalibur® check valves are available in a wide range of sizes and pressure ratings and in a variety of metals to meet most check valve requirements.

DLC® Flanged Check Valves

DLC® Flanged Check Valves

The DFT® Model DLC® is a corrosion resistant, dependable, versatile and economical spring assisted, in-line check valve for a wide range of applications. Whether the fluid is liquid, gas or steam, the DLC® provides tight shut-off and protects other equipment in the system from water hammer. Its stainless steel construction insures a long service life. Inconel® X-750 spring is standard.

Basic-Check® Threaded In-Line Check Valves

Basic-Check® Threaded In-Line Check Valves

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.

Restrictor Threaded In-Line Check Valves

Restrictor Threaded In-Line Check Valves

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.

SCV® Threaded In-Line Check Valves

SCV® Threaded In-Line Check Valves

The DFT® Model SCV® is a corrosion resistant, dependable, versatile and economical spring-assisted, in-line check valve for a wide range of applications. Whether the fluid is liquid, gas or steam, the SCV® provides tight shut-off and protects other equipment in the system from water hammer.

Vacuum Breaker Threaded In-Line Check Valves

Vacuum Breaker Threaded In-Line Check Valves

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.

ALC® Wafer Check Valves

ALC® Wafer Check Valves

The ALC® is an in-line, spring assisted, single guided “wafer” check valve designed to prevent “water hammer” and “reverse” flow. The lightweight compact design fits between mating flanges and meets API 594 Face-to-Face dimensions. The ALC® is an easy to maintain check valve for applications involving liquids, gases or steam. Tapped holes are provided in the body for lifting lugs to assist with installation.

FBC™ Insert Wafer Check Valve

FBC™ Insert Wafer Check Valve

The FBC™ is a compact, lightweight, insert wafer check valve that easily installs between two flanges. The in-line, spring assisted design prevents “water hammer” and “reverse flow”. The FBC™ contains all of the proven features of the Basic-Check® valve developed by DFT® over 60 years ago.

GPV® Wafer Check Valves

GPV® Wafer Check Valves

GPV® Wafer Check Valves feature an in-line spring assisted design to prevent flow reversal for liquids and gases. The edge guided disc and center guided stem ensure that the soft seated disc will always find its home and provide bubble tight shutoff while the 316 stainless steel construction provides superior corrosion protection.

WLC® Wafer Check Valves

WLC® Wafer Check Valves

The DFT® Model WLC Wafer style Silent Check Valve is a lightweight, spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combinations.
