The Flomatic 2438S6-2 888S6 8" 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:

Body: 316 Stainless-Steel

Poppet & Seat: 316 Stainless-Steel

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

Design: Silent, spring-loaded, center-guided

Flange Rating: ASME Class 150 only

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

Max Temperature: 200°F (93°C)

Connection: 8" Wafer, ASME 300# Flange Dimensions (ASME 150# rated)

Weight: 85 lbs

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.

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 for durability, performance, and long service life in demanding pumping applications.
