Proportional Valves

Proportional valves are sometimes referred to as I/P or E/P convertors. They convert a variable current or voltage signal into a proportional compressed air output. We offer a range of functions including open loop control, closed loop control, fail freeze options as well as ATEX options and the ability to program some of the functions and parameters.
