Check Valves

Water hammer is a relatively common problem that is often only briefly touched upon in engineering school curriculums. This DFT webinar Water Hammer- What is it? How do I prevent it in my facility? explains what water hammer is and steps to take to prevent or mitigate its occurrence. Read more...

DFT® non-slam check valves are designed to solve reverse flow, vertical flow, and water hammer issues in critical applications. Download our Check Valve Catalog to discover the right solution for your system. Read more...

The DFT® model PDC® and model GLC® are our most in-demand check valves that meet API-6D. They provide tight shut-off and protect other equipment in the system from reverse flow, chattering, and water hammer. They install horizontally or vertically, and provide superior reliability with a long maintenance life. Read more...

Swing check valves are probably the most misunderstood valve in
the municipal water works industry. What causes a check valve to
slam? How can we prevent it? How does the design of a swing check
valve make it susceptible to slam? Why are there so many closure
devices available?
To answer those questions, read the white paper today. Read more...

DFT’s PDC® Check Valve: Designed for reciprocating compressors

The PDC® has a pulse-dampening 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. Meets API 6D. Read more...

The Tideflex^® Mixing System (TMS) Brochure gives an overview of the system which is known for eliminating short-circuiting, requiring no outside energy source and virtually no maintenance, resulting in cost savings over a long life span. Read more...

Tideflex^® Effluent Diffuser Nozzles are used to prevent intrusion of unwanted sand, sediment, saltwater and marine growth into effluent outfall pipelines. A summary of unique benefits of the nozzle is presented in the new Tideflex^® Effluent Diffuser Nozzles for Multiport Effluent Outfalls Brochure. Read more...

The Tideflex^® Systems video features all four systems including the Tideflex^® Effluent Diffuser System; Tideflex^® Aeration Mixing System; Tideflex^® Hydraulic Recirculation & Mixing System; and the Tideflex^® Mixing System for Potable Water (TMS). This video highlights the rugged construction of these systems an... Read more...

This DFT® model WLC® Wafer Check Valve provides reliable, low-maintenance service for a wide range of fluids and pressure/temperature combinations. It's lightweight, spring-assisted, center-guided, non-slam check valve. Read more...

DFT’s ALC® and WLC® Wafer Style Check Valves are designed to mitigate water hammer and are the answer to unreliable double door/butterfly check valve problems. These reliable, low-maintenance axial flow check valves are for a wide range of fluids and pressure/temperature combinations.

• No more door springs or hinge pin failures...
