The API 602 Flanged 150lbs Forged Steel F304 Swing Check Valve is a high-strength non-return valve designed for smaller-bore piping systems. Unlike cast valves, the forged (F304) body offers superior structural integrity and resistance to thermal fatigue. Featuring ASME Class 150 flanges with a Raised Face (RF), it automatically prevents backflow using a swinging disc. It is a reliable choice for chemical processing and steam services where leak prevention is vital.
