Direct acting solenoid valves, also known as zero rated solenoid valves are electro-mechanical valves that are used to control the flow of liquid or gas. These direct operated solenoid valves convert electrical signals into a mechanical movement, by sending the signal to a coil, allowing movement to occur inside the valve.
Direct operated solenoid valves are available in various configurations, including 3/2 way and 2/2 way valves. Two way NC (normally-closed) direct acting solenoid valves have a spring that holds the core against the seal. While two-way NO (normally-open) zero rated solenoid valves have a fixed core which is usually in the bottom section of the armature tube. Three-way direct acting solenoids work in a similar way.
At MGA Controls, we also stock a range of high performance direct acting solenoids, that are suitable for use in extremely high or low pressure and temperature environments. Available in a range of seal and body materials, including stainless steel and brass, these valves are suitable for use with a wide range of media, including water, air, oils, fuel and aggressive or corrosive chemicals and steam.
Direct acting solenoids are used when there is no line pressure. They are commonly used in cleaning line applications, when a pump supplies bursts of water through a line. In order to operate efficiently, zero rated solenoid valves require a direct connection between the solenoid core tube and the valve’s opening/closing mechanism. MGA Controls stocks a wide range of direct acting solenoid valves, from leading, global manufacturers.
