The Flomatic 2437S6 888S6 6" silent wafer-style check valve is a spring-loaded, center-guided check valve designed for 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 a metal-to-metal seating design that is not drip-tight.

Specifications:

Poppet & Seat: 316 Stainless-Steel

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

Design: Silent, spring-loaded, center-guided

Flange Rating: Dual-rated ASME Class 150 & 300

Operation: The spring-loaded poppet begins to close as flow decreases and fully seats at zero velocity, minimizing reverse flow and hydraulic shock. The metal-to-metal seat provides durability in high-cycle applications where tight shutoff is not required.

Applications: Municipal water systems, HVAC, irrigation, industrial process applications, and pumping systems where silent operation and long service life are required.
