The Hybrid Valve™ from Blacoh combines the steady flow control of a pulsation dampener and the regulation of a back pressure valve to deliver the performance of both. In a metering pump system, using a back pressure valve alone might do nothing to improve fluid flow. As a single unit, the valve takes up less space and has fewer leak points for improved functionality and lower maintenance costs.
When installing pulsation dampeners and back pressure valves in any pumping system, location and proximity are important. A back pressure valve installed in series with a dampener can negate the dampening effect if the valve is opening and closing before the dampener is able to capture a full pulse.
This quick-opening effect can also create too much gain within the back pressure valve, resulting in inefficiency and chatter. “By combining the dampener and back pressure valve into a single harmonious unit,” said Yeghnazar, “we’ve eliminated the most common issues with installation for a more efficient, simplified system.”
