Description

OMB Forged Piston Check Valves – ½” to 2”, Class 800 & 1500, A105N/F316L

OMB forged piston check valves are designed for high-performance non-return flow control in critical piping systems. Manufactured in Italy, these compact forged valves are offered in sizes from ½” to 2” and pressure classes 800 and 1500, making them ideal for high-pressure and high-temperature applications. Constructed from durable A105N carbon steel or corrosion-resistant F316L stainless steel, these valves are engineered to prevent backflow using a guided piston mechanism that ensures tight sealing and consistent operation. The design includes Reduced Bore (RD) or Full Bore (FB) options, and end connections such as Raised Face (RF), Threaded (NPT), and Socket Weld (SW). These valves comply with international standards and are widely used in oil & gas, refining, petrochemical, and power generation applications.
