Blacoh Hybrid Valve

The future of metering pump systems. Introducing the world's first combination pulsation dampener & back pressure valvve:

The new patent-pending 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 and functionality of both. Why install and maintain two pieces of equipment when the Hybrid Valve™ does the same- only better.


The patent-pending Hybrid Valve was engineered to proven principles with state-of-the-art design for optimum performance and maximum efficiency.

In a metering pump system, using a back pressure valve alone (orange) does nothing to improve fluid flow. When put in series with a pulsation dampener, the flow improves significantly (red) but, results still can’t match the performance of the single construction Hybrid Valve for the steadiest flow (blue).


Location and proximity are key when installing pulsation dampeners and back pressure valves in any pumping system. 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 engineered unit, we’ve eliminated the most common issues with installation for a more efficient, simplified system.


Watch our Engineering Manager David McComb demonstrate the Hybrid Valve™ with a metering pump.

He will guide you through the performance of the pump with a pulsation dampener alone, then in series with a back pressure valve, and finally with the new Hybrid Valve™.

Understand the fluid dynamic principles to see why the Hybrid Valve™ delivers the best performance and giving your system the protection that it deserves.
