The difference between Solenoid valve and electric valve
Solenoid valves and electric valves are important executive components in industrial piping control and are used in a wide range of applications. The main difference between the two is as follows: 1. Working principle Solenoid valve is composed of a solenoid, valve and valve body. When the coil is energized or de-energized, the spool is actuated to allow the fluid to pass through the valve body or be cut off. Electric valve is driven by the motor stem, driven spool action, to achieve the fluid through or cut off. 2. Valve Type Solenoid valve is usually two two-way valve body has an inlet and an outlet connected to the pipeline, there are two kinds of control: normally open type (when the valve is closed, the fluid is cut off), normally closed type When the valve is open, the fluid through the valve) Electric valve is through the electric actuator to rotate the valve plate angle, or lift the valve plate to control and regulate the valve off and control the flow of the pipeline. 3. Control method Solenoid valve driven by the coil can be instantly opened or closed, but only fully open or closed. Electric valve is driven by a motor, open or close the action to complete a longer time, by the actuator input current and voltage signals to regulate the flow.
