FloMatic has recently presented a new stainless steel submersible check valve, the Model 80S6CL-VFD, suited for VFD controlled pumps.
Standard check valves produce noises when a VFD goes to low flow, causing premature wear and eventual failure. This valve is designed to minimize flow losses and hydraulic shocks in the pumping system.
It features an AISI316 stainless steel body that incorporates North American Specialty Products patented groove lock type pipe connections called Certa-Lok® to support deep set pumps. An exclusive stainless steel guided poppet system ensures that the valve automatically adjusts noiselessly from high to very low flow rates. The radiuses of the valve seat allow a self-cleaning “one point swiping action” by the radius-edged custom molded rubber seal disc. All internal parts are made from corrosion-resistant materials.
It is able to work up to 27.5bar and 80°C. It is available from 50 to 200mm in size.
