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.

Valve Installation
Observe all installation warnings, cautions and notes provided in the Fisher HP and HPA Control Valve Instruction
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 .
