The Flomatic 2243BT 402BT 5" globe-style silent check valve is a spring-assisted, center-guided check valve built with an epoxy-coated ductile iron body for quiet, non-slam performance in Class 150 flanged piping systems. This model is designed to reduce reverse flow and minimize water hammer in pumping applications.

Specifications:

Body: Epoxy-coated ductile iron

Trim: Unleaded bronze

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

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

Flange Rating: ASME Class 150

Max Pressure: 300 PSI @ 150°F

Max Temperature: 200°F (93°C)

Connection: 5" Flanged, ASME 150#

Weight: 51 lbs

Approvals: NSF/ANSI 61 & 372 (2"–12" sizes only)

Operation: As flow decelerates, the spring-assisted disc begins to close and fully seats at zero velocity, helping reduce reverse flow and hydraulic shock. The center-guided design supports stable operation under variable flow conditions.

Construction: An epoxy-coated ductile iron body provides strength and corrosion resistance. Internal components are engineered for long service life in demanding water and pumping applications.

Applications: Municipal water systems, booster pump stations, HVAC, irrigation, and industrial pumping systems where silent operation and reduced water hammer are required.

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