1-4. Nameplate A nameplate as shown in Figure 1-4 is posted on each control valve. The nameplate indicates the model number, valve size, pressure rating, trim material, date of manu.facture and other major specifications of the control valve. Before installing the con.trol valve, make sure that the specifications indicated on the nameplate conform with the conditions of use. The nameplate indicate also the product number (PROD.NO.) of the control valve. Please mention this number also when consulting an Azbil Corp. agent for replacement of parts or other modification of the control valve.

Chapter 2. Installation 2-1. Maximum lifting loads of eyebolts The diaphragm case has a pair of lifting eyebolts. These eyebolts primarily are for lifting the actuator alone. When using the eyebolts for other purposes (such as lifting an actuator bed to its valve body or other components), note that the allowable maxi.mum lifting loads of the eyebolts are as shown in the following table. Table 2-1 Maximum lifting loads of eyebolts Note: The eyebolts may be used to lift the actuator together with its valve buy (cast globe valve) of up to pressure rating “Class 600”. When doing this, be...

(1) Check that there is no leak from air piping. (2) Check that the bolts and nuts of the diaphragm case are not loose. Standard tight.ening torques are as follows: (3) Tighten the packing flange nuts to prevent leak from the gland packing chapter. Standard tightening torques are as shown in Table 2-2. Table 2-2 Tightening Torques of Packing Flange Nuts Note: The tightening torques mentioned in the above are only to give you reference values. Note that tightening torques may vary depending on the type of packing. PTFE Yarn Packing Graphite + Graphite Yarn V PTFE + PTFE Yarn Packing...

Squeeze Screw Lubricator Handwheel Figure 2-3 Lubricator for High Pressure Valve (Class 600 or higher) Figure 2-2 Lubricator (Class 600 or under) Lubricating procedure (a) prepare grease of the type indicated on the nameplate. (b) Tightly close the lubricator handwheel. (c) Remove the squeeze screw, apply grease, and set the squeeze screw. (d) Loosen the lubricator handwheel and drive grease by turning the squeeze screw. (e) Repeat the procedure of 0), (c) and (d) until turning of the squeeze screw becomes heavier. Tightly close lubricator handwheel. (5) Pressurizing valve, check that there...

Chapter 3. Inspection and Maintenance Inspect and service the actuator as follows: (1) Tightening the gland: Tighten the gland once in every 6 months or thereabout. The tightening procedure is as given in Section 2-3-(3). Lubricating the gland: (2) Lubricating the gland once in every 6 months or thereabout. The lubricating procedure is as given in Section 2-3-(4). (3) Check for hunting of valve Position: Refer to Chapter 10 ''Troubleshooting.'' (4) Check for abnormal noise and vibration: Refer to Chapter 10 ''Troubleshooting.''

Chapter 4. Disassembly and Assembly This Chapter covers the disassembly and assembly procedures of the actuator for its overhaul or modification. 4-1. Detaching actuator from valve body See Figure 4-7. (1) Apply to the actuator an air pressure so that the valve position pointer is at a point of 10% - 20% above the fully closed point. (2) Loosen the clamping-bolts of the stem connector, remove the stem connector, and detach the actuator stem from the valve stem. (3) Remove the clamping-nut of the yoke. (4) Raise the actuator to detach it from the valve body. Precautions: or detaching the...
