Before installing the valve in the pipeline, thoroughly clean the line of all dirt, welding chips, scale, oil or grease, and other foreign material. the valve. 2. through the valve body in the direction selected in Figures 5 through 10 on pages 8 or 9. Leak detection port should be located at the lowest point in the installed position. 3. A three-valve bypass must be used to permit removal of the control valve from the line without shutting down the system. 4. To detect if leakage or breakage of the diaphragm has occurred, a pressure gauge may be installed in the 1/8 NPT port (14) in the bonnet, see Figures 1, 2, and 3, on page 6.! WARNING AIR PIPING 1. For an air-to-extend actuator (air-to-close action), connect the actuating air pressure line to the 1/4 NPT opening in the upper diaphragm case. For an air-to-retract actuator (air-to-open action) connect the actuating air pressure line to the 1/4 NPT opening in the lower diaphragm case. 2. Use 1/4 in (6.4 mm) O.D. tubing or equivalent for all air lines. If air line exceeds 25 ft (8 m) in length, 3/8 in (9.5 mm) tubing is preferred. Air lines must not leak. Air pressure should not exceed 35 psig (2.5 barg). BODY REMOVAL (Not Required For Actuator Reversal) through 4 below. DO NOT SQUEEZE BODY IN VISE 1. For Fail-Closed Action (air-to-open), stroke actuator up to take pressure off from the diaphragm pushing against seat. For Fail-Open Action (air-toclose), no need to stroke actuator. 2. Remove bonnet screws (18) for size NPS 1 or clamp (11) for sizes NPS 1-1/2 or 2. 3. Lift bonnet assembly (2) with actuator from valve body (1). 4. Once disassembled; for Fail-Closed Action ONLY, release pressure from actuator to be able to unscrew diaphragm, for Fail-Open Action you must pressurize actuator to unscrew diaphragm. This is the only action required for inspection or cleaning. 5. Stroke actuator down to exert some pressure and remove the diaphragm (8) by unscrewing diaphragm (8) from compressor (5). Remove bonnet o-ring (15) (NPS 1-1/2 and 2 valves only). Wipe diaphragm (8) with a clean soft cloth and examine for wear. 6. Inspect body sealing surfaces. If valve leakage becomes excessive, replacement of diaphragm (8) may be necessary, ACTUATOR REMOVAL To remove actuator, unscrew drive nut (9) and loosen jam nuts (27). Unscrew piston stem (3) from actuator stem. 3
84000 Control Valve BONNET DISASSEMBLY Remove diaphragm (8) and bonnet o-ring (15) (NPS 1-1/2 and 2 valves only) per instructions under Body Removal section above. Proceed as follows: 1. Turn bonnet assembly (2) over. 2. Pry out retaining ring (7) using a small flat screwdriver. 3. Remove wave springs (6), compressor (5) and drive mechanism (4). 4. Next push out piston-stem assembly (3). Clean and replace as required. BONNET REASSEMBLY For correct orientation of sub-assemblies to bonnet refer to Figure 4, page 6, exploded view. 1. Insert piston stem assembly (3) into bonnet (2). 2. Orient drive mechanism as shown in Figure 4. 3. Verify that machined surfaces at the end of the rectangular plates are in full contact with the machined recess inside bonnet (2). IMPORTANT: Verify that the recessed roller bearings in the drive mechanism (4) rest against the of the piston stem assembly (3). 5. side resting against the extended roller bearings. 6. Drop wave springs (6) into place, prongs down; the NPS 1 valve requires two (2) wave springs. The NPS 1-1/2 and 2 valves require three (3) wave springs. Oppose spring opening 180 o when installing wave springs. 7. Retain all parts by installing retaining ring (7) into bonnet groove. 8. Gap in retaining ring (7) should align with crest of wave spring (6). 9. Push down on bonnet assembly to drive piston Instruction Manual to provide some tension. 10. Insert o-ring (15) (NPS 1-1/2 and 2 valves only), so that it rests on the retaining ring (7). 11. Lubricate screw thread and cone of diaphragm (8) with sterile food grade lubricant. 12. Screw diaphragm (8) onto compressor (5) snugly. 13. Place complete bonnet assembly onto the valve body (1). for proper centering. B. 1 bolted flange configuration should be tightened for metal-to-metal contact between tightening body bolts on the NPS 1. C. For NPS 1-1/2 and 2 valves, apply clamp (11) and tighten the nut gradually, checking for even amount of PTFE over the body, between the bonnet and clamp, for proper centering. D. The gap between the clamp ends should be approximately 1/2 or less for proper diaphragm compression. DO NOT OVERTIGHTEN E. Examine through port B to be sure diaphragm is centered on seating area. VALVE CALIBRATION After valve is assembled per previous instructions, install properly configured actuator (see ACT.IM actuator instructions), making sure to engage piston stem (3) as much as possible into actuator stem. Tighten drive nut (9). (Refer to Figure 5, Pages 8 & 9 1. Calibration of Fail-Close (air-to-open) Actuator. Apply 50 psi air or nitrogen to port B. Apply 3 psi air signal to actuator. A. Slowly turn piston stem assembly (3) out of 4
Instruction Manual B. Check valve for leaks with 50 psi air under diaphragm (port B ), leakage should be less than 1 cc/min. The valve should start to leak the actuator. If it takes more than minimum pressure to open, then screw piston stem assembly (3) further into actuator stem. If valve is not tight at 3 psi signal, screw the piston stem assembly (3) out of the actuator stem some more. Next, calibrate zero on travel indicator scale with minimum pressure signal to actuator. Check for full travel at maximum pressure signal. If leak persists, increase the force on the clamp (11) to compress the diaphragm (8) by tightening clamp nut. If size NPS 1 valve, tighten bolts 84000 Control Valve to compress the diaphragm (8) by tightening clamp nut. If size NPS 1 valve, tighten bolts CLOSE PROPERLY, INCREASE CLAMP COMPRESSION AROUND THE DIAPHRAGM CLOSE PROPERLY, INCREASE CLAMP COMPRESSION AROUND THE DIAPHRAGM 2. Calibration of Fail-Open (air-to-close) Actuator. Apply 50 psi air pressure or nitrogen to port B. Apply 15 psi air signal to actuator. A. Slowly turn piston stem assembly (3) out of B. Check valve for leaks with 50 psi air under diaphragm (port B ), leakage should be less than 1 cc/min. The valve should start to leak the actuator. If it takes more than maximum pressure to open, then screw piston-stem (3) further into actuator stem. If valve is not tight at 15 psi signal, screw the piston-stem (3) out of the actuator stem some more. Next, calibrate zero on travel indicator scale with maximum pressure signal to actuator. Check for full travel at minimum pressure signal. If leak persists, increase the force on the clamp (11) 5
