ASTM A182 F316L Piston Check Valve, API 602, 1/2 IN, 800 LB

Key Specifications / Features

The Forged Steel Piston Check Valve is designed per API 602 and crafted from stainless steel ASTM A182 F316L, ensuring superior corrosion resistance and durability. Sized at 1/2 inch (DN15) with Class 800 LB (PN130) rating, it is built for high-pressure applications. Featuring a bolted bonnet for secure sealing and FNPT threaded ends for easy installation, this valve prevents backflow with a robust piston mechanism.

Forged Steel Check Valves are built to meet international standards like API 602 and ASME B16.34. They are designed to minimize flow resistance and pressure drop, ensuring maximum efficiency. These valves are meant for horizontal installation only, with a lapped and screwed seat ring that provides a tight seal for long-lasting service. The valve disc is carefully designed, precisely machined, and guided to ensure automatic shutoff even at zero pressure. Available in both swing and piston styles, these valves have a compact design and low-emission service, offering reliable performance in various applications.
