Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operation to avoid personal injury.

To avoid personal injury and parts damage, do not apply pressure that exceeds the Maximum Operating Diaphragm

Pressure (table 1) or produces a output thrust on the stem greater than the Maximum Actuator Stem Force (table 2 and 3).

Use pressure-limiting or pressure-relieving devices to prevent the operating pressure from exceeding the Maximum

Operating Diaphragm Pressure.

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

media.

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,

pressure drop, and controlled fluid conditions.

Responsibility for the safety of process media and the compatibility of valve materials with the process media rests solely

with the purchaser and end user. Since some valve body/trim materials combinations are limited in their pressure drop and

temperature ranges, do not apply any other conditions to the valve without first contacting your Emerson Automation

Solutions sales office.

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

instruction manual.

A 3024C diaphragm actuator is normally shipped mounted on a valve. Refer to the appropriate valve instruction

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

actuator on the valve, perform the Actuator Mounting procedure given below. For information on mounting the

positioner, refer to the appropriate positioner instruction manual.

Note

The 3024C actuators are designed to mount on push‐down‐ to‐close valves. Do not mount these actuators on any other type of

valve without first contacting your

Mounting the Actuator on the Valve

The following procedure describes how to mount a 3024C actuator on a push‐down‐to‐close valve so that the actuator

stem and valve stem thread engagement allows full travel and proper shut‐off. Refer to table 4 and figures 6 and 7 for

actuator dimensions. Key numbers referenced in the following steps are shown in figures 8 and 9.

1. Provide a temporary method of applying diaphragm air loading pressure to the diaphragm to move the actuator

stem during adjustments.

2. Provide a vice or some other method of supporting the valve and the weight of the actuator during assembly.

3. Push the valve stem down until the valve plug is fully closed.

4. Screw the two stem locknuts (key 52) to the lower end of the valve stem thread.
