Key Specifications / Features
This API 602 forged steel lift check valve in Class 800 rating is constructed from ASTM A105N carbon steel with a black painted exterior. It adopts a bolted bonnet design and butt weld ends for robust pipe joining. The valve automatically prevents reverse flow in high-pressure steam, oil and gas piping. Compact and durable, it suits high-temperature industrial service. Its lift-type disc reliably opens with forward flow and seats tightly to block backflow, meeting ASME B16.34 design requirements for critical process pipelines.
