Safety shut off valves, slow opening and fast closing with hydraulic or pneumatic actuator
The VMH type valve is a safety shut off valve for gaseous media operated by hydraulic actuator. It is suitable for gas blocking and releasing controls, as required in the main pipe of gas power burners, atmospheric gas boilers, industrial kilns and gas consuming appliances.
When the actuator is energized, the valve opens slowly (some seconds); as soon as power supply stops, the valve closes immediately (<1 sec). It is qualified for continuous service (100% ED).
The hydraulic actuator can be replaced with a pneumatic actuator (VMP series) if compressed air is available in the plant.
