Description
The Fisher HP Startup Trim kits are available for NPS 8 and larger sizes and include options for hydro testing, flushing,
and chemical cleaning of the system. The hydro kit is intended to be used so that the upstream piping can be tested at
the required pressure for body and inlet piping pressure class without over pressurizing any attached lower pressure
class piping or equipment downstream. The flushing kit allows for pipes to be cleaned upstream and downstream of
the valve by allowing dirt, scale, or debris to pass through the valve without causing damage to the valve trim used in
normal operation. The chemical cleaning kit is used when cleaning the pipeline with a low velocity, chemical flush of
the pipeline.

Manual (D101634X012). Follow the instructions provided in the Fisher HP and HPA Control Valve Instruction Manual
for valve assembly installation
Maintenance
WARNING
Avoid personal injury or property damage from sudden release of pressure or uncontrolled process fluid. Before
performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the power actuator loading pressure and relieve any spring precompression.
D Use lock‐out procedures to be sure the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out when removing the packing hardware or packing rings, or when loosening the
packing box pipe plug.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

(D101634X012). Follow the Trim Removal instructions provided in the Fisher HP and HPA Control Valve Instruction
Manual. See figure 5 for the HP assembly drawing
Installation of Startup Trim Kits
Inspect the valve to ensure all parts and gaskets have been removed and the valve body is free from foreign debris.
Inspect all parts for defects and cleanliness; remove any burrs on metal valve components. Visually inspect the interior
of the valve for abnormal wear, signs of erosion, or scoring if the valve has been in service. Inspect the gasket surfaces
of the valve body, bonnet, and trim to verify they are not damaged and are free of imbedded gasket material.
Installation of Flushing and Hydro Trim Kits
1. Install the seat ring flat sheet gasket (key 12) in the lower gasket groove in the valve body (key 1), making sure the
gasket is centered in the groove and the bottom of the gasket is flush with the mating surface in the body.See
figure 4.
2. For Flushing Trim: Install eyebolt (3/8-16 UNC-2B) in to the hole on the top of the cage (key 2), as shown in figure 2.
Then proceed with step 3, lifting the cage using the eyebolt.
For Hydro Trim: Install threaded rods (1/4-20 UNC-2B) in to the holes on the top of the cage (key 2). Install hoist
rings, nuts or eye bolt on to the threaded rod, as shown in figure 3. Then proceed with step 3, lifting the cage using
the hoist rings on the threaded rods inserted in the top of the cage

extruding from the packing box. Snug the nuts together, see table 1 for recommended jam nut (key 47) torque
values. These will be removed after flushing/hydro testing.
11. Lower the bonnet (key 18) and stem/nut assembly (key 46, key 47) over the bonnet studs (key 13) and onto the
valve body (key 1), making sure the bonnet (key 18) skirt will not damage the bonnet spiral wound gasket (key 11),
or the three-cage spiral wound gaskets (key 43). When lowering the bonnet (key 18) into the body (key 1), take care
to ensure that the bottom diameter guides properly with the cage (key 2) and the outside diameter of bonnet
guides properly with body (key 1).
Note
The bonnet might not sit flush on the bonnet gasket until the bolts are completely tightened. Once tightened properly, the bonnet
will contact metal-to-metal with the valve body.
For bolt sizes larger than 1-1/2 inch, install washers (key 40) over the bonnet studs, taking care not to introduce
lubricant between the washer and the bonnet surface. Lubricant should be present between the seating surface of
the bonnet stud nut and the washer. Turn the nuts (key 14) onto the studs (key 13) until hand tight.
12. Torque bonnet nuts (key 14) in a crisscross pattern with no more than 1/4 of the nominal torque specified in table
2. When all nuts are tightened to that torque, increase the torque by 1/4 of the specified nominal torque and repeat
the crisscross pattern. Repeat the above until all nuts are tightened to the specified nominal torque value. If any nut
still turns at the final torque, tighten every nut to the final torque again. For odd number of bolts, tighten the
