Direct acting solenoid valves, also known as zero rated solenoid valves, are electro-mechanical valves that are used to control the flow of liquids or gases.

This type of valve is directly actuated by the solenoid and does not require any difference in pressure between the inlet and outlet ports in order to operate; they can therefore function from 0 bar upwards. Direct acting solenoids adhere to simple working principles. They do not use a diaphragm – their seal is part of the moving core – and they will remain closed even when no pressure is being applied. This is in contrast to a pilot operated valve, which requires some pressure for the valve to stay closed.

We keep a wide range of directing acting valves of a variety of brands, in 1/4″ & 1/2″ sizes.
