The Flomatic 2427XT 812XT 3" threaded check valve is an all 316 stainless-steel, three-piece check valve designed for high-temperature service where durable metal-to-metal seating is required. This model incorporates a PTFE O-ring and threaded FNPT connections.

Specifications:

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

Seal: PTFE O-ring

Seat Type: Metal-to-metal (not drip-tight)

Design: Spring-assisted, threaded, three-piece body

Max Pressure: 300 PSI

Max Temperature: Metal Seating Only 400°F (200°C)

Connection: 3" FNPT x FNPT

Weight: 24 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 intended for applications where resilient sealing is not required.

Applications: Industrial process systems, high-temperature water and fluid 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.
