The Flomatic 2420X 812X 1/2" wafer-style check valve is an all 316 stainless-steel, spring-assisted check valve designed for installation between ASME Class 150 and 300 flanges where applicable. This model features a metal-to-metal seating design for high-temperature, high-pressure service.

Specifications:

Body, Disc, Spring & Retainer: 316 Stainless-Steel

Seat Type: Metal-to-metal

Design: Silent, spring-assisted, wafer style

Max Pressure: 600 PSI (metal seat)

Max Temperature: -20°F (-30°C) to 660°F (350°C)

Connection: 1/2" Wafer, ASME 150# / 300#

Weight: 0.2 lbs

Operation: The spring-assisted disc begins closing as flow decelerates and fully seats at zero velocity, reducing reverse flow and minimizing water hammer. The metal-to-metal seat is suitable for demanding applications where resilient sealing is not required.

Applications: Industrial process systems, high-temperature water and steam service, HVAC, and pumping applications requiring durable stainless-steel construction.

Flomatic Quality: For more than five decades, Flomatic has manufactured engineered check valves recognized for reliability, precision machining, and long service life in demanding applications.
