EH (1-1/2x1 through 8x6) December 2014 Instruction Manual D100394X012 Installation WARNING Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury. To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve assembly where service conditions could exceed the limits given in this manual or on the appropriate nameplates.
Instruction Manual EH (1-1/2x1 through 8x6) D100394X012 December 2014 3. The control valve must be installed with the actuator vertical above the valve body for proper operation. Flow through the valve must be in the direction indicated by the flow arrow (key 15, figure 17, 18, or 20) on the valve body. 4. Use accepted piping and welding practices when installing the valve in the line.
Instruction Manual EH (1-1/2x1 through 8x6) D100394X012 December 2014 Maintenance Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance frequency depends on the severity of service conditions. This section includes instructions for packing lubrication, packing maintenance, adding packing rings, replacing packing, trim removal, valve plug maintenance, lapping seats, and trim replacement.
Instruction Manual D100394X012 EH (1-1/2x1 through 8x6) December 2014 WARNING Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however some readjustment will be required to meet specific service conditions. Check with your process or safety engineer for any additional measures that must be taken to protect against process media. Packing Lubrication CAUTION Do not lubricate graphite packing. Graphite packing is self-lubricated.
Instruction Manual EH (1-1/2x1 through 8x6) D100394X012 December 2014 Replacing Packing Key numbers referred to in this procedure are shown in figure 16 unless otherwise indicated. 1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body, and drain the process media from both sides of the valve. Remove the cap screws in the stem connector, and separate the two halves of the stem connector.

For extension bonnets, also remove the baffle (key 2) and retaining ring (key 35). 9. Clean the packing box and the following metal packing parts: packing follower (key 13), packing box ring (key 11), spring or lantern ring (key 8, figures 4 and 16), and, for single arrangements of PTFE V-ring packing only, special washer (key 10, figures 4 and 16). 10.
Instruction Manual EH (1-1/2x1 through 8x6) D100394X012 December 2014 When all nuts are tightened to that torque value, increase the torque by one fourth of the specified nominal torque and repeat the crisscross pattern. Repeat this procedure until all nuts are tightened to the specified nominal value. Apply the final torque value again and, if any nut still turns, tighten every nut again. Figure 5.
Instruction Manual EH (1-1/2x1 through 8x6) D100394X012 December 2014 If desired, a tool can also be machined for a valve of specific size and valve class using the dimensions shown in figure 9. Machine the tool from a material listed in figure 9 or from a material with a yield strength of at least 827 MPa (120,000 psi). Using a tool of lower strength material may result in damage to the seat ring retainer or valve body threads.
