The Flomatic 2437S6R 888S6R 6" silent wafer-style check valve is a spring-loaded, center-guided check valve designed to provide quiet, non-slam operation in variable flow and VFD-controlled pumping systems. This model features an all 316 stainless-steel body, poppet, and seat with an EPDM resilient seal for drip-tight performance.

Specifications:

Body: 316 Stainless-Steel

Poppet & Seat: 316 Stainless-Steel

Seal: EPDM (resilient, drip-tight)

Design: Silent, spring-loaded, center-guided

Flange Rating: Dual-rated ASME Class 150 & 300 wafer

Max Pressure (ASME 150#): 275 PSI @ 100°F

Max Pressure (ASME 300#): 475 PSI @ 100°F

Max Temperature: 200°F (93°C)

Connection: 6" Wafer, ASME 150#/300#

Weight: 36 lbs

Operation: As flow decreases, the spring-loaded poppet begins to close and fully seats at zero velocity, reducing reverse flow and minimizing water hammer. The resilient EPDM seat provides drip-tight sealing at low pressures, while a metal-to-metal backup seat protects the elastomer at higher differential pressures.

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

Flomatic Quality: For more than five decades, Flomatic has been a trusted manufacturer of engineered check valves and backflow products used worldwide. Flomatic valves are designed with a focus on durability, performance, and long service life in demanding pumping applications.
