DFT
DFT® has been making the in-line check 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®, DLC®, DSV®, Excalibur®, FBC™, GLC®, GPV™, PDC®, SCV® and WLC® styles of in-line silent check valves. Each of these DFT® in-line check valves addresses the particular needs of a modern day customer.
DFT’s 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. 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 customer problems by improving performance and extending service life. The “Check Valve Doctor™” continues to grow from satisfying these needs and solving problems.
The 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 the valve that’s right for you.
