Flomatic 3711CS 92CS 10" Lever & Weight Cushioned Swing Check Valve

The Flomatic 3711CS Model 92CS 10" lever and weight cushioned swing check valve is designed for non-potable water service where controlled closure and dependable backflow prevention are required. This valve features an epoxy-coated ductile iron body, a rubber seat with standard Nitrile (Buna-N) sealing, a stainless-steel shaft, and an external lever and weight with a sealed end cushion system for an adjustable rate of valve closure.

Specifications:

Standard: AWWA C508

Body: Epoxy-coated ductile iron

Seat: Rubber with Nitrile (Buna-N) seal (standard)

Flange Rating: ASME Class 150

Connection: 10" Flanged, ASME 150#

Weight: 470 lbs

Operation: Under forward flow, the clapper opens; as flow decelerates and reverses, the valve closes to limit reverse flow. The lever and weight promote responsive closure, while the sealed end cushion system provides a controlled, cushioned finish to the closing stroke to help minimize slam and reduce water hammer.

Construction: The epoxy-coated ductile iron body is built for durability in demanding water system environments. A stainless-steel shaft supported by corrosion-resistant bearings and sealed by an adjustable packing gland supports long service life. The cushioned closure assembly uses a sealed cylinder to compress air during the final portion of closing travel, providing non-slam operation with field-adjustable closure characteristics.

Applications: Pump stations, industrial and municipal utility systems, irrigation, and general water service where a lever-and-weight swing check valve with adjustable cushioned closure is preferred to reduce hydraulic shock.

Flomatic Quality: Flomatic manufactures engineered check valves recognized for consistent performance, durable construction, and long service life in demanding pumping applications.

Not for potable water.
