Differences in Actuation Method:Įlectric valves are actuated, or opened and closed, by motors. Another advantage of solenoid valves is that they can be reset when the power is off while a reset device needs to be installed on the electric valve to achieve such a function. Solenoid valves are actuated by an electromagnetic coil, so it’s more susceptible to damage from voltage shock. Usually, the solenoid valve has a very small flow coefficient and working pressure difference. Solenoid valves can’t meet this requirement. The half-open position provides some control over the flow rate of the medium in the pipeline. With electric valves, you can control the degree to which the valve opens or closes, meaning there are three (or more) states: open, closed, and half-open/half-closed. Thanks to their electric activation, they are often used in fluid process systems that require computer connection and automated controls. When an electric current is presented to the solenoid, it builds a magnetic field that pulls the metal armature against a spring, opening or closing the valve. Solenoid valves actuate with an electromagnet. Solenoid valves open and close faster than electric valves, so they are usually used in applications with frequent switching between open and closed positions, or in applications with low flow rates and low pressure. Differences in Valve Function:Įlectric valves usually actuate using force from motors which are more resistant to voltage shock than solenoids. The 4 Main Differences Between Solenoid Valves and Electric Valves 1.
Let’s dive right in to learn more about solenoids and electric valves! We shared their information in the list below. However, the experts at Adamant Valves were kind enough to explain the 4 key differences between these two types of sanitary valves.
Specifying the differences between the solenoid and electric valves can be a confusing task because both function similarly. What is the difference between solenoid valves and electric valves?
