EH Valves NPS 8 through 14 Instruction Manual July 2014 D100392X012 CAUTION The valve configuration and construction materials were selected to meet particular pressure, temperature, pressure drop, and controlled fluid conditions. Because some body/trim material combinations are limited in their pressure drop and temperature range capabilities, do not apply any other conditions to the valve without first contacting your Emerson Process Management sales office.
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 Principle of Operation Key numbers referenced in this section are shown in figure 12 for the EHD valve and in figure 14 for the EHT valve. EHD and EHT valves are balanced designs. When they are opening or closing, pressure registers on top of the valve plug (key 3) through the registration holes in the plug.
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 8. After all maintenance is complete, refer to the Trim Replacement procedure to assemble the valve body. Note If the valve has ENVIRO-SEAL™ live-loaded packing installed, see the Fisher instruction manual titled ENVIRO-SEAL Packing System for Sliding-Stem Valves (D101642X012) for packing instructions.
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 A lubricator or lubricator/isolating valve (figure 2) is recommended for PTFE-impregnated composition packing. The lubricator or lubricator/isolating valve is installed in place of the pipe plug in the bonnet. Use a good quality silicon-base lubricant. Do not lubricate packing used in oxygen service or in processes with temperatures over 260_C (500_F).
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 Key numbers referred to in this procedure are shown in figure 11 unless otherwise indicated. 1. Remove the stem connector cap screws shown in figure 3, and separate the two halves of the stem connector. Then exhaust all actuator pressure, if any was applied, and disconnect the actuator supply and any leakoff piping. 2. Remove the hex nuts (key 26) and remove the actuator from the bonnet (key 1).

Use this rigging to secure the cage to the bonnet or hoist to prevent damage or injury should the cage suddenly separate from the bonnet. CAUTION When lifting the bonnet (key 1), be sure that the valve plug and stem assembly (keys 3 and 4, figure 12 or 14) remains on the seat ring (key 6, figure 12 or 14).

Instruction Manual D100392X012 EH Valves NPS 8 through 14 July 2014 12. Slide the bonnet over the stem and onto the bonnet studs (key 13, figure 12 or 14). Note Proper performance of the bolting procedures in step 13 compresses the cage gaskets (key 11, figure 12 or 14) enough to seal the body-to-bonnet joint. The prelubricated hex nuts (key 14, figure 12 or 14) referred to in step 13 can be identified by a black film coating on the nut threads.
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 For spring-loaded PTFE V-ring packing: Tighten the packing flange nuts until the shoulder on the packing follower (key 13) contacts the bonnet (key 1). For other kinds of packing, except ENVIRO-SEAL and HIGH-SEAL: Tighten the packing flange nuts to the maximum recommended torque shown in table 5. Then, loosen the packing flange nuts and retighten them to the recommended minimum torque in table 5.
Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 1. With the valve plug (key 3) removed per the Trim Removal procedure, proceed as appropriate: For the EHD valve, the piston rings (key 8) are each in two sections; remove the sections from the grooves in the valve plug. For all EHT valves, work the retaining ring (key 10) off the valve plug with a screwdriver. Carefully slide the backup ring and seal ring (keys 9 and 8) off the valve plug.
EH Valves NPS 8 through 14 Instruction Manual July 2014 D100392X012 5. After lapping, again disassemble as necessary, clean the seating surfaces, reassemble, and test for shutoff. Repeat the lapping procedure if necessary. Trim Replacement After all trim maintenance has been completed, reassemble the valve by following the numbered steps below. Be certain that all gasketed surfaces are clean.
Instruction Manual D100392X012 EH Valves NPS 8 through 14 July 2014 6. Install the valve plug into the cage. 7. Install the other cage gasket (key 11) between the cage and the bonnet. CAUTION Failure to comply with good bonnet-to-body bolting practices and the torque values shown in table 6 may result in cage crushing, cage diameter reduction, and/or bonnet deformation. Cheater bars or slug wrenches should not be used for this procedure.

Instruction Manual EH Valves NPS 8 through 14 D100392X012 July 2014 CAUTION To avoid excessive leakage and seat erosion, the valve plug must be initially seated with sufficient force to overcome the resistance of the Bore Seal plug seal and contact the seat ring. You can correctly seat the valve plug by using the same force calculated for full load when sizing your actuator.
