Duplomatic Proportional Valves

Duplomatic proportional valves include pressure control, flow control, directional, explosion-proof and high-response valves

Proportional valves help to deliver efficiency, speed, accuracy, repeatability and programmable control to electrohydraulic applications.

The various models are available with or without on-board electronics (OBE), feedback and a closed loop. Duplomatic Motion Solutions also offers many digital electronic cards to control proportional valves.
