Valves of type 4WRPH-750 are direct operated high-response valve in servo quality with electric position feedback and robust design. The valves are actuated on one side and in their deactivated condition take a 4/4 fail-safe position. They are suitable for use in the wood industry and in installations with aggravated environmental conditions
