The Flomatic 2242S6R 402S6R 4" globe-style silent check valve is a spring-loaded, center-guided check valve designed to provide quiet, non-slam operation in Class 150 flanged 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: Globe-style, silent, spring-loaded, center-guided

Flange Rating: ASME Class 150

Max Pressure: 275 PSI @ 100°F

Max Temperature: 200°F (93°C)

Connection: 4" ASME 150# Flanged

Weight: 40 lbs

Operation: As flow decreases, the spring-assisted poppet begins to close and fully seats at zero velocity, minimizing reverse flow and hydraulic shock. The EPDM resilient seat provides drip-tight sealing under low and moderate differential pressures while maintaining quiet operation.

Applications: Municipal water systems, booster stations, HVAC, industrial process systems, and other pumping applications requiring silent operation and dependable backflow prevention.

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