What is a motorised on/off control valve?
A control valve regulates the fluid by changing the size of the flow passage in response to a signal from a controller. Control valves make pressure, temperature, flow and level control possible in any process that carries a fluid, and let the cold water, hot water, steam, superheated water and gas a plant produces at the cost of energy be carried and controlled without loss.
What does on/off operation mean?
On/off operation describes a control system in which a device is either fully open or fully closed, with no intermediate position. This type of control is generally used in simple systems where a device has to be switched on or off according to a single condition or input.
The electric actuator removes the need for a compressed air line, which makes this valve the practical choice in plants where air is not available or where the valve stands far from the machine room.
