Flomatic has released its new Wafer Style Silent Check Valve compatible with VFD Controlled Pumps in an all 316 stainless steel valve body, stainless steel poppet, seat ring, and spring. The uniquely designed valve is the only of its kind that can be close coupled with a butterfly valve, eliminating the need for a spool piece. The valve is designed to minimize flow losses and hydraulic shocks in the pump system.
The patented spring loaded poppet system is guided in an oversized sleeve for stability, resulting in a quiet and efficient operation regardless of flow rate. In addition to a quiet operation, the valve design provides a fast closure, which helps prevent check valve slam and alleviate water hammer. Ideally suited for demanding clean water VFD controlled pump booster systems, Model 888S6VFD is available in six different sizes (2- through 6-inch).
