Description

Douglas Chero Forged Piston Check Valves – ½” to 2”, Class 150 to 2500, A105N/F316L/LF2/F22

Douglas Chero forged piston check valves are precision-engineered for non-return flow protection in high-pressure pipelines. Built in Italy using high-grade forged materials, these valves are designed to prevent reverse flow in process systems handling steam, gas, oil, and corrosive fluids. The piston-type internal design provides tight shut-off and consistent performance under variable pressure conditions. Available in sizes from ½” to 2” and pressure ratings from Class 150 to Class 2500, these valves are manufactured in A105N carbon steel, F316L stainless steel, LF2 for low-temperature applications, and F22 alloy steel for high-temperature and high-pressure service. With Reduced Bore (RD) and Full Bore (FB) options and end connections including Raised Face (RF), Threaded (NPT), and Socket Weld (SW), they meet international standards for performance and reliability. These check valves are ideal for upstream, refining, power generation, and chemical service lines.
