Pumps and compressors are used in a wide range of industries such as pharmaceutical, food & beverage, petrochemical, natural gas, power generation, chemical industries, and building maintenance. Pumps and compressors transport fluids and compressible gases, respectively, from one location to another. Axial flow check valves are an important protection for pumps and compressors as they… Read More

Severe service valves are used in applications involving periodic or extended exposure to extreme temperatures, high pressures, and/or abrasive, corrosive, or erosive compounds. Due to the harsh operating conditions to which they subjected, these valves often feature specialized construction materials and body designs to ensure they maintain their integrity during use. At DFT®, we’ve manufactured… Read More

Swing check valves use a hinged swinging disc to block and control the movement of fluid in a system. As they are used to prevent the reverse flow of fluids or gases, any failure can lead to leakage, loss of pressure, contamination, overflow, and, in the most severe cases, complete system failure. Below we discuss… Read More

Hydraulic shock—more commonly known as “water hammer”—occurs when the flow within a pipe is suddenly forced to change direction, which creates a pressure wave that can be characterized by a loud knocking or banging sound. In piping and process systems, water hammer often happens upon closing a valve to stop or redirect flow. It’s important… Read More

DFT® Inc. is proud to announce the implementation of new advanced robotics technology to streamline the manufacturing process at our Exton, PA headquarters. This high technology robot provides the efficient production of lapped discs, which is an important manufacturing process at DFT, allowing for the tight metal-seated shutoff of our axial flow, spring-assisted check valves.… Read More
