Flow proportional valves

A flow proportional valve lets the controller change actuator speed continuously with an electrical signal, instead of fixing it with a manual throttle. With a built-in pressure compensator, the flow stays stable even when the load changes, which is what makes speed repeatable in presses, test benches, lifting and injection moulding machines.

The HD-2FRE series is the alternative to Rexroth 2FRE6, 2FRE10 and 2FRE16: sizes 6, 10 and 16, up to 160 L/min and 210 bar. Size it on the maximum flow of the actuator and on the pressure drop you can accept.

To drive the solenoid you need an electronic card: see the electronic drivers for open-loop control.
