Goodwin Dual Plate Check Valve – A350 LF2 / F316, Viton Seat
The Goodwin Dual Plate Check Valve with ASTM A350 LF2 body, F316 stainless steel internals, and Viton (FKM) soft seat is engineered for reliable backflow prevention in demanding industrial applications. Designed to API 594 standards, this compact and lightweight valve ensures fast closure, low pressure drop, and long service life.
The low-temperature carbon steel A350 LF2 body provides excellent toughness and strength, while F316 stainless steel discs and components offer superior corrosion resistance. The Viton seat ensures tight shut-off performance, making this valve ideal for hydrocarbon, chemical, and process fluid services.
With its retainerless dual plate design, the valve minimizes leakage paths and reduces maintenance requirements. Suitable for a wide range of pressure classes and sizes, Goodwin dual plate check valves are widely trusted in oil & gas, petrochemical, power, marine, and industrial piping systems.
