Blacoh Fluid Control’s Hybrid Valve receives US patent
According to the company, the hybrid valve is the world’s first combination pulsation dampener and back pressure valve. It combines the steady flow control of a pulsation dampener with the regulation offered by a back pressure valve in a single item of equipment.
Within a metering pump system, the use of a back pressure valve alone is not sufficient to improve fluid control. When added in series with a pulsation dampener, the flow significantly improves, however according to Blacoh tests, performance is unable to match that of the Hybrid Valve for the steadiest flow.
Additionally, as a single unit, the valve requires less space and has fewer leak points for improved functionality and lower maintenance costs.
