Blacoh releases ‘world’s first’ combination pulsation dampener and back pressure valve

Blacoh Fluid Control has announced the release of the ‘world’s first’ combination pulsation dampener and back pressure valve, which it has named the Hybrid Valve.

The new valve is intended to combine the steady flow control of a pulsation dampener and the regulation of a back pressure valve to deliver the performance and functionality of both in a single piece of equipment.

Blacoh president Andrew Yeghnazar said: “Blacoh Industries as an organisation has explored many new ideas to solve existing problems in the industry as well as fuel growth for our organisation and those we serve. As a result, we are pleased to launch another new and innovative product to improve pumping systems and reduce costs.” 

The new Hybrid Valve has been designed to maximise efficiency and flow. Placing a back pressure valve in series with a pulsation dampeners improves flow significantly in a metering pump system. However, Blacoh claims that its own performance tests show these combinations can’t match the performance of the single construction Hybrid Valve.

When installing pulsation dampeners and back pressure valves in any pumping system, location and proximity are key. 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.”
