ASTM A182 F316 Lift Check Valve, 3/4 Inch, 2500 LB, API 602
Key Specifications / Features
This forged ASTM A182 F316 lift check valve is NPS 3/4, Class 2500 with socket weld ends, built per API 602 and ASME B16.34. It adopts pressure seal bonnet construction for ultra-high-pressure working conditions. The lift piston design automatically blocks reverse flow to protect pipelines. It complies with ASME B16.11 for weld ends and API 598 testing. Ideal for corrosive chemical, oil, and gas services requiring reliable non-return performance under severe high pressure.
