Flomatic 2433 888 5" Silent Wafer Check Valve – Metal-to-Metal Seat

The Flomatic 2433 888 5" silent wafer-style check valve is a spring-assisted, center-guided check valve built with an epoxy-coated ductile iron body for quiet, non-slam performance in pumping systems. This model uses a durable metal-to-metal seating design that is not drip-tight and is designed for installation between ASME Class 150 and 300 flanges where applicable.

Specifications:

Body: Epoxy-coated ductile iron

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

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

Approvals: NSF/ANSI 61 & 372

Max Pressure: ASME 150#: 300 PSI @ 150°F / ASME 300#: 500 PSI @ 150°F

Max Temperature: 200°F (93°C)

Connection: 5" Wafer, ASME 150# / 300#

Weight: 25 lbs

Operation: As flow decelerates, the spring-assisted poppet begins to close and fully seats at zero velocity, reducing reverse flow and minimizing water hammer. The metal-to-metal seat is intended for applications where resilient, drip-tight shutoff is not required.

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

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.

Note: 2"–6" sizes are dual rated to fit between both ASME Class 150# and 300# flanges.
