FBV Dual Plate Check Valves – ½” to 16”, Class 150 to 1500, USA

FBV dual plate check valves are engineered for high-performance flow control in applications requiring non-return functionality with reduced pressure drop and compact form factor. Manufactured in the USA, these valves are available in sizes from ½” to 16” and pressure ratings from Class 150 up to Class 1500. The dual plate design features two spring-loaded plates that open with forward flow and close tightly upon reverse flow, minimizing water hammer and flow disruption. Ideal for oil and gas, petrochemical, power generation, and water treatment applications, FBV check valves are built from durable materials such as carbon steel and stainless steel, with wafer or lug-type end connections to fit standard flanged piping.
