• It comes equipped with a magnetic clutch which protects the motor during stalling and ensures a constant output force to maintain positive close-off condition.
• This electric valve actuator features selectable direct and reverse action for easy setup and installation.

Standards and Approvals:

• UL
• CSA

Frequently Asked Questions:

Q. What is the cycle time of this actuator?

A. This actuator has a cycle time of 70 seconds.

Q. What is the input impedance required for Johnson Controls VA-7152-1001 electric valve actuator?

A. This actuator requires an input impedance of 100000 Ohm.

Q. What is the difference between electric and pneumatic actuators?

A.

• The major difference between an electric and a pneumatic actuator is the driving force of their operation.
• Air supply for pneumatic actuators must be between 60 and 125 PSI, whereas electric actuators are used when there is no air supply available.
