Since its initial development, the check valve has evolved from a classified request from the U.S. Navy to becoming a staple in flow control systems, allowing operators to easily stop reverse flow and water hammer while providing tight metal-to-metal closure. Some of the first all-stainless steel valves were engineered for use with cryogenic liquids and… Read More

Steam plays an important role in just about every industrial segment we can think of.  Chemical processing, mining, petroleum production and refining, power generation, Pulp and Paper, and textile, are all just some of the industries that use steam every day to do what they do. Maintaining high-quality Steam carries a number of benefits including… Read More

Check valves are used in pipelines, hoses, and tubing to prevent backflow of liquids and gases. In the gas industry, this helps protect equipment from damage, reduce excessive vibration, and maintain steady production. A major use for check valves is normalizing the flow of gas during reciprocating compressor discharge in long-distance pipelines. Other natural gas… Read More

Pulse-dampening check valves, or PDC® valves, are designed for installation on the discharge side of a gas or air reciprocating compressor and feature a pulse-dampening chamber. With this pulse-dampened design, during the momentary pressure and flow increases and reductions that occur with a reciprocating compressor’s cycles, the PDC® valve’s disc remains in the open position,… Read More
