DFT®, formerly known as Durabla® Fluid Technology, has been making in-line check valves and severe service control valves for over 70 years. It started with a customer’s 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, other customers’ needs led to the development of the ALC®, BNC®, DLC®, DSV®, Excalibur®, FBC™, GLC®, GPV™, PDC®, SCV® , TLW® and WLC® styles of in-line silent axial flow check valves. Each of these DFT® in-line check valves addresses the particular needs of today’s customer.
Our objective is to solve check valve problems and prevent check valve failures. DFT® has learned by listening to customers like you that each industry has special needs that can exceed other check valve designs. We specialize 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 customer problems by improving performance and extending service life. The “Check Valve Doctor™” continues to grow from satisfying these needs and solving problems.
