Blacoh Back Pressure & Pressure Relief Valves
Blacoh's engineering team has carefully redesigned the back pressure valves and pressure relief valves from the inside out. We believed that it was possible to produce a better valve that can still be priced competitively, while providing more value to our users and customers. Fully protect your pumping system from pressure damage with these reliable, CNC precision machined units.
What's New?
The new Blacoh back pressure valve features patent-pending flow stabilization technology to improve the consistency of flow and pressure downstream of the valve. Traditional back pressure valves have a similar design to pressure relief valves which are designed to discharge a high volume of fluid once they open. Testing shows that the opening and closing of a traditional back pressure valve creates interruptions in the flow and a corresponding change in line pressure. Blacoh's new valve varies the output as pressure changes, and has been optimized to provide a balance of flow, back pressure stability and downstream pressure stability.
No More Chatter!
The patent-pending flow stabilization technology in the new Blacoh back pressure valve also eliminates dreaded "valve chatter". What normally creates chatter? Because most back pressure valve designs are based on pressure relief valves, there is too much flow when they open. This causes the back pressure to drop rapidly and the valve slams shut. Once the valve has shut the output from the deadheaded PD pump causes the pressure to shoot up rapidly, forcing the valve to open again. This happens many times per second, resulting in a loud, chattering valve with inconsistent performance and a short life. The new Blacoh design meters out the flow without allowing too much flow or slamming shut, eliminating the chatter.
