Our pressure balanced proportional valves are the premium solenoid proportional valves in the industry. With the ability to handle fluctuating inlet pressures, and some amount of back pressure, your cracking current and overall valve performance will remain stable and relatively unchanged. We are able to accomplish this by mechanically balancing the active pressures internally by rerouting the acting inlet pressure. 

​

No matter the change in inlet pressure, the valve seat will see equal acting force on both sides of the seat, therefore negating the change in pressure and maintaining your performance.
