ECv Electric Bellows Vacuum Isolation Valves
Model: ECV

Overview
Overview
The Series ECV Electromagnetic Cv valve 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. The Electromagnetic Cv valve 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. Each Electromagnetic Cv valve includes a coil saver circuit integrated with the input power cable. 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. Valve actuation can be switched between normally open and normally closed without any additional parts. Solenoid options are available in either 12 VDC or 24 VDC. The Electromagnetic Cv valve is offered in the angle and inline configurations with multiple fitting options. The body is comprised of high grade, corrosion resistant, non-magnetic 304 stainless steel. The formed bellows assembly is made of 321 corrosion resistant stainless steel. Metal bonnet seals of either nickel or copper are available as standard options. Kalrez®, Silicone, Viton® and Chemraz® are also options for both the bonnet seal and nose piece. For remote indication of valve position, a limit switch option can be specified within the part number ordering system.
