JOHNSON CONTROLS VA-7152-1001 Electric Valve Actuator, 90 Inch-lb, Proportional

Johnson Controls VA-7152-1001 electric valve actuator provides proportional control of valves with up to 3/4 inch stroke in ventilating, heating and air conditioning applications.

Working Mechanism:

• VA-715x Series actuators precisely position the valve using a magnetic clutch and a reversible synchronous motor.
• 90 lb of force in either direction may be consistently produced by this combination. Even if the actuator loses power, the shutoff force is maintained.
• The shutdown force is decreased and the valve modulates when the controller sends a signal to the actuator, telling it to move in the opposite direction.
• To ensure tight valve shutdown and account for seat wear, the magnetic clutch maintains a consistent load at the end of travel.

Features:

• Johnson Controls VA-7152-1001 electric valve actuator features a unique yoke design capable of generating force output up to 90 lb for proportional control of valves.
• 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.
