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 3024C actuator without being fully trained and qualified in valve, actuator, and

accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to

carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you

have any questions about these instructions, contact your Emerson Process Management sales office before

proceeding.

Instruction Manual D103048X012 3024C Actuator May 2011 Installation 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.

Instruction Manual 3024C Actuator May 2011 D103048X012 Figure 4. Actuator Mounting Components for Assembly with a Valve W8484‐1 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 between the actuator stem and other parts of the valve assembly.

Instruction Manual 3024C Actuator D103048X012 May 2011 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.

3024C Actuator May 2011 Instruction Manual D103048X012 k. If the valve travel is not correct repeat the stem connector procedure. Apply approximately 0.5 bar pressure above the upper setting of the spring range to the bottom of the diaphragm, remove the stem connector and then repeat steps d to j. Note When disassembling the stem connector on Air‐to‐Open constructions it is essential to apply enough air pressure to the underside of the diaphragm to lift the valve plug off its seat.

For a top‐loaded 3024C Air‐to‐Close actuator, reduce the diaphragm air pressure to zero and remove the piping or tubing from the connection in the upper diaphragm casing (key 16). For a bottom loaded 3024C Air‐to‐Open, apply air pressure to the diaphragm to open the valve.

Install the new bushing (key 6) and assemble with the cheese head screws (key 7) onto the lower diaphragm casing (key 1). Use a torque of 0.4 NSm (3 lbfSin). 2.

3024C Actuator May 2011 Instruction Manual D103048X012 Note Be sure to use the long cap screws (key 21) first, installing them on opposite sides of the diaphragm casing. Tighten them evenly, using a criss‐cross pattern to ensure a proper seal. 5. Mount the actuator on the valve in accordance with the Installation Procedures. Changing the Actuator Action The actuator can be changed from a 3024C Air‐to‐Open to a 3024C Air‐to‐Close action or vice versa.

If the handwheel assembly was removed from the actuator yoke, position the assembly within the yoke so that the eight mounting holes on the assembly align with those on the yoke and fit the cap‐screws (key 113) tightening to 28 NSm (20 lbfSft).
