585C Actuator October 2013 Instruction Manual D102087X012 Actuator with Spring Return (figure 3) 585C size 25 & 50 actuators are available with bias springs in two configurations. The 585C actuator, with the bias spring under the piston, fully retracts the actuator stem upon loss of cylinder pressure. The 585C actuator, with the bias spring on top of the piston, fully extends the actuator stem upon loss of cylinder pressure. No additional parts are required to convert from one actuator type to the other.

Instruction Manual D102087X012 585C Actuator October 2013 accessories and/or valve. Use caution during lifting and handling to prevent slippage, swinging, faulty equipment connections, or sudden shock loads. CAUTION To avoid damage to actuator parts and difficult operation of actuator handwheels, open the bypass valve before using a handwheel. If manual operation is required, the actuator should be equipped with a manual handwheel.
PAGE 12
585C Actuator Instruction Manual October 2013 D102087X012 1. If not already removed, remove the stem connector (key 12) by loosening the cap screws (key 14). 2. Thread the stem connector nuts (keys 13 and 15) onto the valve stem, and run the nuts to the bottom of the valve stem threads. 3. Push the valve plug stem until the valve plug is closed for push-down-to-close valve plug action. 4. Place the actuator on the bonnet of the valve and secure the actuator tightly to the bonnet with the yoke locknut.
PAGE 13
Instruction Manual D102087X012 585C Actuator October 2013 Size 60-130 Actuator Mounting The following procedure describes how to mount a 585C size 60 to 130 actuator on a push-down-to-close valve so that the piston stem to valve plug stem connection allows full travel and proper shutoff. Key numbers referenced in the following steps are shown in figures 9 through 12.
PAGE 14
585C Actuator Instruction Manual October 2013 D102087X012 5. Once the total travel is adequate, tighten the stem connector (key 12) securely, lock the stem locknuts (key 15) against the connector, and adjust the indicator scale (key 19) on the yoke to show correct valve plug position. 6. Provide a gauge to measure the pressure to the actuator. Make a final adjustment of the actuator or its positioner to set the starting point of valve travel and to obtain full travel for the given instrument range.

Instruction Manual 585C Actuator D102087X012 October 2013 a. To open or close the valve manually or to position the valve at any point in the stroke, regardless of the cylinder pressure. The tapered pin is inserted during manual throttling operation. b. To act as a travel stop to limit full opening or closing of the valve but not both at the same time. The tapered pin is left out when the assembly is used as a travel stop. c.

585C Actuator Instruction Manual October 2013 D102087X012 Replacing Handwheel Housing O-Ring or Thrust Bearings (Sizes 25 & 50) Perform this procedure if inspecting or replacing the handwheel housing O-ring, handwheel thrust bearings, or any other handwheel parts located above the cylinder (key 1). Inspection or replacement of the cylinder O-ring, handwheel stem, or handwheel stem jam nut (key 57, 56, or 52) are covered in the Replacing Seals, Changing Action, or Changing Bias Spring(s) procedure.

Instruction Manual D102087X012 585C Actuator October 2013 3. Lubricate the inside surface of the operating nut (key 46) with lithium grease (key 24). Install the operating nut with the attached neutral indicator, and the handwheel stem washer (key 45), onto the handwheel stem (key 56) and secure with the handwheel stem cap screw (key 60). Tighten the cap screw to 169 NSm (125 lbfSft). 4. Place the bottom set of thrust bearings (key 39) on top of the cylinder (key 1).
PAGE 18
585C Actuator October 2013 Instruction Manual D102087X012 CAUTION When performing the following step, set the cylinder on a protective surface to prevent damage to the cylinder surfaces. 3. Remove the cylinder (key 1). Set the cylinder on a protective surface to prevent damage to the cylinder surfaces. With a handwheel construction, inspect the cylinder O-ring (key 57) and replace it if necessary, applying lithium grease (key 24) to the replacement O-ring. 4.

Instruction Manual D102087X012 585C Actuator October 2013 2. To achieve the desired construction (either a direct-acting or a reverse-acting 585C actuator), perform one of the following assembly procedures (a, b, or c, as appropriate): a. For 585C actuators (bias spring retracts the piston rod) (figures 4 and 5), center the inner bias spring, if used, (key 17 per table 6 or 7) around the center boss in the yoke (key 6).
PAGE 20
585C Actuator October 2013 Instruction Manual D102087X012 Maintenance (Sizes 60-130) WARNING To avoid personal injury or property damage caused by cylinder fracture as a result of piston impact, install the stem connector securely before supplying pressure to the positioner. Use only a regulator-controlled air supply to move the actuator piston so that you can install the stem connector. Do not use the positioner to move the actuator piston before installing the stem connector.
PAGE 21
Instruction Manual 585C Actuator D102087X012 October 2013 4. Insert a screwdriver in the two slots on the lower edge of the cylinder casting and pry the cylinder loose from the yoke. Remove the cylinder, being careful not to mar the cylinder wall. 5. The piston (key 3) and actuator stem (key 10) will come out with the cylinder. The piston can then be removed by forcing it out the open end of the cylinder. 6. Unscrew the seal bushing (key 110 or 26), in the upper end of the yoke (key 6). 7.

To remove the actuator stem (not shown), loosen the stem connection (key 12) and pull the actuator stem out the top of the sleeve assembly (key 104). 10. Remove the sleeve by screwing it out of the sleeve assembly (key 104). 11. Unscrew the seal bushing (key 110) to inspect the O-rings (keys 9 and 27).
