3024C Actuator

Introduction

Scope of Manual

This instruction manual provides information on installation, adjustment, maintenance, and parts ordering for the Type 3024C actuator (figure 1) for sizes 30 to 45 and 30E to 45E.

Note

This manual assumes throughout that the valve construction is “push-down-to-close.”

Do not install, operate, or maintain a Type 3024C actuator without first D being fully trained and qualified in valve, actuator, and accessory installation, operation and maintenance, and D carefully reading and understanding the contents of this manual. If you have any questions about these instructions contact your Emerson Process Managementt sales office before proceeding.

Description

The Type 3024C direct acting (extends stem/air-to-close) actuator (figure 8) and the reverse acting (retracts stem/air-to-open) actuator (figure 9) are spring-opposed pneumatic diaphragm actuators that provide automatic throttling or on-off operation of sliding-stem control valves.

The actuator will position the valve plug in response to varying pneumatic loading pressure on the actuator diaphragm. Figure 2 shows the operation of

travel stop can also be fitted (figures 11 and 12).

The Type 3024C ATC (air-to-close) actuator springs are located under the diaphragm plate and they fully retract the actuator stem for fail action upon loss of diaphragm casing pressure. The Type 3024C ATO (air-to-open) actuator springs are located on top of the diaphragm plate and they fully extend the actuator stem upon loss of diaphragm casing pressure. The actuator is mounted on the valve by means of a cast yoke.

WARNING

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

Personal injury or equipment damage caused by sudden release of pressure may result if the actuator assembly is installed where service conditions could exceed the limits given in tables 1, 2, and 3 or the appropriate nameplates. To avoid such injury or damage, provide a relief valve for overpressure protection as required by accepted industry and governmental codes and good engineering practices.

To avoid parts damage, do not use a normal operating pressure that exceeds the Maximum Diaphragm Casing Pressure (see table 1) or produces a force on the actuator stem greater than the Maximum Allowable Output Thrust (see table 2 or 3) or Maximum Allowable Valve Stem Load.

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

HAND-

WHEEL

OUTPUT

FORCE

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 Process Management 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 Type 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.

CAUTION

The Type 3024C actuators are designed to mount on push-downto-close valves. Do not mount these actuators on any other type of valve without first contacting your Emerson Process Management sales office.

Mounting the Actuator on the Valve

The following procedure describes how to mount a Type 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

between the actuator stem and other parts of the valve assembly.

Perform one of the following procedures as appropriate:

For a Type 3024C Air-To-Close Actuator with a Push-Down-to-Close Valve:

a. Carefully place the actuator on the valve so that the yoke boss fits over the valve bonnet.

b. Screw the yoke lock nut onto the bonnet and tighten.

c. Lift the valve plug off the seat by the correct valve travel for the valve. This is stated on the nameplate or in table 1.

d. Place the stem connector half (key 50) approximately halfway between the actuator and valve stems but observing the F dimension in table 5 so that any positioner lever (if fitted) is horizontal at mid-travel. Be sure that the actuator and valve stem threads are engaging the threads of the stem connector by at least the distance of one diameter of the stem.

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.

WARNING

When moving the actuator stem with diaphragm loading pressure use caution to keep hands and tools out of the actuator stem travel path. Personal injury and/or property damage is possible if something is caught

CAUTION

Be sure that the length of the actuator stem and the valve stem in the connector (key 50) is equal to or greater than the diameter of that stem. Incomplete engagement of either the valve or actuator stem in the stem connector can result in stripped threads or improper operation.

In the following procedure do not rotate the valve plug while it is seated. This may damage the seating surface and cause excessive leakage. While making adjustments, use tools carefully to avoid damaging the valve stem. A damaged stem could cut the packing and allow leakage through the packing box.

e. Install the other half of the stem connector and insert the socket screws and nuts and tighten them.

f. Screw the two stem locknuts (key 52) up the valve stem to the stem connector and tighten. Do not over tighten.
