Cast steel piston check valves, or "one-way" valves, are a modification of standard lift check valves. Utilizing a piston-shaped plug rather than a cone, the high-performance designs of cast steel check valves are used to prevent backflow by reacting to the line fluid in your petrochemical, gas or oil system.
With metal-to-metal seats, quick piston opening, leak-proof operation and superior thermal resistance, American Petrochem's piston check valves come in a variety of sizes and configurations to fit your application requirements. In order to withstand high-pressure surges or frequent flow changes, our piston valve discs and seats are designed to align perfectly-even in the most demanding petrochemical environments.
Choose cast steel check valves when you need a ferrous metal that endures a lifetime of temperature shifts and drastic pressure changes. Looking for another material option? American Petrochem also carries piston check valves in stainless steel and cast iron.
While we stock a full inventory of valve configurations and premium brands, we understand that you may have a need for a custom design. If your cast steel piston check valve requires customization, contact our engineering specialists for lead times and availability. We offer affordable, expedited delivery, and each of our valves is hydro-tested and comes with a comprehensive one-year warranty.
