Coil Saver Circuit Design

The ECv’s coil saver circuit design minimizes the heat typically generated by most conventional electric valves, making it the most suitable option for temperature sensitive gauge isolation. The coil saver circuit offers a more efficient solenoid coil operation by limiting the power usage of the coil, once the valve has been actuated. This in turn allows the valve to operate without excessive heat generation, remaining safe to the touch.


The Electromagnetic Cv™ (ECv) valve is designed for a variety of today’s high-vacuum process needs and is ideal for applications requiring a simple, compact high conductance electric valve. Ideal for pump systems, portable vacuum stands and benchtop analytical systems, the ECv valve installs easily and economically without the need for pneumatic connections, gas bottles, or costly house air facilitization.
