ECv Electric Bellows Vacuum Isolation Valve
ECv Electric Bellows Vacuum Isolation Valve
ECv Electric Bellows Vacuum Isolation Valves can be used in place of any existing Cv valve where electric actuation is preferred over pneumatic or manual actuation. The ECv valve is actuated by a direct current electric power supply, and consequently, does not require the use of a pneumatic system. The ECv valve’s actuation system is retrofittable in any current Cv valve. It features a low profile, linear solenoid mounted to the top of the valve, that serves as the valve actuator. When power is applied to the solenoid, the solenoid is energized, causing the valve to open or close, depending on the configuration.
- NW10 - NW25 or VCR
- Electric actuation applications (12 VDC or 24 VDC)
- 1,000,000 cycle rating (clean environments)
- Flexible actuator assembly design can be configured as normally open or normally closed
- High conductance body and formed bellows design exceeds 1,000,000 cycles See All Features

Features
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.
Applications
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.
