Flomatic 2242BTR2 402BTR2 4" Ductile-Iron Silent Check Valve – Class 250

The Flomatic 2242BTR2 402BTR2 4" globe-style silent check valve is a spring-assisted, center-guided check valve constructed with an epoxy-coated ductile iron body for quiet, non-slam operation in Class 250 flanged systems. This model features a bronze resilient seating surface with a Nitrile (Buna-N) seal and stainless-steel spring for reliable sealing and durability.

Specifications:

Body: Epoxy-coated ductile iron

Seat: Bronze resilient seat with Nitrile (Buna-N) seal

Spring: Stainless-Steel

Design: Silent, spring-assisted, center-guided, globe style

Flange Rating: ASME Class 250

Max Pressure: 400 PSI @ 150°F

Max Temperature: 150°F (65°C)

Connection: 4" Flanged, ASME 250#

Weight: 44 lbs

Operation: As flow decelerates, the spring-assisted disc begins to close and fully seats at zero velocity, minimizing reverse flow and hydraulic shock. The resilient bronze seat supports improved sealing performance in demanding applications.

Applications: Municipal water systems, high-pressure pumping stations, industrial process systems, and utility applications requiring Class 250 flanged silent check valves.

Flomatic Quality: For more than five decades, Flomatic has manufactured engineered check valves trusted worldwide for reliability, performance, and long service life in demanding pumping applications.
