Products ASME Flomatic
Flomatic has announced a wafer-style Silent Check Valve compatible with clean water VFD-controlled pumps in an all 316 stainless steel valve body, stainless steel poppet, seat ring and spring.
The Flomatic check valve is said to be the only of its kind that can be close coupled with a butterfly valve, eliminating the need for a spool piece. The unit 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.
The model 888S6VFD is available in six different sizes from 2 to 6 in. Units are designed to fit ASME Class 125/150 & ASME 250/300 flanges and meet MSS-SP 125 standards.
Additional technical specifications include a pressure maximum of 400 psi and a maximum operating temperature of 82°C, as well as being certified NSF/ANSI 61 & 372.
