Flomatic has a new Wafer Style Silent Check Valve that is compatible with VFD controlled pumps in an all 316 stainless steel valve body, stainless steel poppet, seat ring and spring.

The Silent Check Valve is the only of its kind that can be close-coupled with a butterfly valve, eliminating the need for a spool piece, Flomatic said in a press release.

Made by Flomatic, 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 (two-inch through six-inch). Model 888S6VFD two-inch through six-inch are designed to fit ASME Class 125/150 & ASME 250/300 flanges and they meet MSS-SP 125 standards.

Additional technical specifications include a pressure max of 400 PSI, a maximum temperature of 180 F (82 C).Certified NSF/ANSI 61 and 372 and covered by a three-year warranty, model 888S6VFD is manufactured under a certified ISO 9001 and 14001 quality management system at Flomatic’s Manufacturing Plant in Glens Falls, N.Y.
