Overview

This forged steel check valve combines bolted flange connections with a forged body for strength in higher-pressure service. The internal disc lifts or swings open under forward flow and reseats automatically when flow reverses, protecting pumps and upstream equipment without any manual operation. Flanged raised face or RTJ ends give a secure, leak-resistant joint, making it a dependable non-return valve for oil and gas, refining and general process pipelines.
