Principle of Operation

Piston movement is accomplished by loading air pressure on one side of the piston, and unloading air pressure from

the other side of the piston. If no positioner is used with the control valve, a loading device, such as a 4-way switching

valve, must be provided. Such a device is not furnished with the actuator.

Refer to the separate valve positioner instruction manual for the 1061 actuator principle of operation with positioner.

Installation

When an actuator and valve are shipped together, the actuator is normally mounted on the valve. Follow the valve

instructions when installing the control valve in the pipeline. If the actuator is shipped separately or if it is necessary to

mount the actuator on the valve, perform the procedures presented in the Actuator Mounting section.

WARNING

To avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation

operations.

To avoid personal injury or property damage caused by bursting of pressure retaining parts, be certain the service

conditions do not exceed the limits given in table 1 or on the nameplate. Use pressure limiting or pressure relieving devices

to prevent the cylinder pressure from exceeding the maximum allowable cylinder operating pressure.

Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this

instruction manual.

Actuator Mounting

Use the following steps to connect a valve and actuator that have been ordered separately, or if the valve or actuator

were separated for maintenance purposes.

Key numbers used in this procedure are shown in figures 8, 9 and 11.
