Combined pulsation damping with a backpressure valve
In July, this company received U.S. Patent 10,353,409 for its Hybrid Valve (photo), said to be the world’s first combination pulsation dampener and backpressure valve. The Hybrid Valve combines the steady flow control of a pulsation dampener and the regulation of a backpressure valve to deliver the performance and functionality of both in a single piece of equipment. In a metering pump system, using a back pressure valve alone does nothing to improve fluid flow. When put in series with a pulsation dampener, the flow improves significantly but, according to company performance tests, results do not match the performance of the single-construction Hybrid Valve for the steadiest flow. Further, as a single unit, the Hybrid Valve takes up less space and has fewer leak points for improved functionality and lower maintenance costs. — Blacoh Industries, Riverside, Calif.
