Since 1943 DFT® Inc. has manufactured world class, problem solving, in-line, axial flow, nozzle style silent check valves and severe service control valves. Our Basic Check® valve was designed and engineered to satisfy the need of our first customers. Over our 70+ year history, other customer requirements have resulted in the development of the ALC®, DLC®, DSV®, Excalibur®, GLC®, PDC®, SCV®, WLC®, and Y-Calibur™ styles of axial flow, non-slam silent check valves.
Our core mission and objective is to diagnose check valve problems, provide solutions and prevent failures. By carefully listening to customers, we've learned that each industry has specific needs that may exceed other check valve designs. That is why DFT specializes in providing in-line check valves that meet customer requirements as opposed to simply meeting line size. In some cases, minor modifications to our valves have solved a customer's problem in addition to improving overall performance and extending the service life of the valve.
DFT in-line check valves can meet the "new" NACE Standards NACE MR0175/ISO 15156 and NACE MR01032003. The ALC®, DLC®, Excalibur®, GLC®, GPV™, PDC®, SCV®, SCV-R®, WLC®, Y-Calibur™ can be constructed of the proper materials depending on the applicable NACE standard.
DFT valves are being utilized in a variety of applications in the following industries: Chemical Processing, Petroleum Production & Refining, Mining, Pulp & Paper, Textiles, Power Generation, Food, Beverage & Drug, Primary Metals, and Building Maintenance.
Whether it is "in stock", or a "custom engineered, special order", the DFT® sales and engineering staff will respond quickly to your requirements. DFT® is the only company that specializes in a broad spectrum of spring assisted; in-line silent check valves with materials ranging from cast iron to exotic alloys, and that are made in America.
