DFT silent check valves are known around the world as the valve to use to prevent or eliminate water hammer problems. Whatever your size, pressure or piping configurations, DFT has a check valve for you. DFT in-line check valves began over 50 years ago with a customers need for a small metal-seated check valve that could be installed in any position while providing tight shut-off. The Basic-Check valve was developed to satisfy that need. Over the following decades, customers needs led to the development of the DLC, Excalibur, GLC, PDC, SCV and WLC styles of in-line silent check valves. DFT learned by listening to customers like you that each industry has special needs that require a specially designed check valve. DFT In-Line Check Valves have been developed for use on liquids, gas or steam in the following industries: Chemical, Food & Beverage, Oil & Gas, Petrochemical, Pharmaceutical, Power Generation, Pulp & Paper, Steel, Textile, Ultra Pure, and Mining. They specialize in providing in-line check valves that meet customer requirements as opposed to simply meeting line size. The Check Valve Doctor continues to grow from satisfying these needs and solving problems.
