3DREP(E)6... L2X type three-way proportional pressure reducing valve

Series of pictures

The 3-way pressure reducing valve type 3DREP 6... is directly actuated by proportional solenoids. They convert an electrical input signal into a proportional pressure output signal.

Specification: 6

Pressure: up to 100 bar

Flow: up to 15 L/min
