Safety Hydraulic Valves

NC automatic reset slow opening fast closing

The VMH-type valve is a shut-off valve for gaseous media operated by a hydraulic actuator.

It is suitable as main safety device for gas blocking and gas releasing controls, as required when operating gas burners, atmospheric gas boilers, industrial kilns, and generally all gas-consuming appliances.

When the actuator gets energized, it slowly opens the valve over a few seconds. Once fully open, the hydraulic pump turns off to minimize power consumption. As soon as the power supply stops, the valve closes immediately (<1 sec).

It is qualified for continuous service (100% ED).
