Pressures and Temperatures
(1)
Maximum Application Temperature
260_C (500_F)
Maximum Application Pressure
Pressure is limited to the maximum valve rating
1. The pressure/temperature limits in this manual, in the valve literature, and any applicable code or standard limitation should not be exceeded.
Removing the Actuator
WARNING
Avoid personal injury from sudden release of process pressure or uncontrolled movement of parts. Before performing any
installation 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 to avoid personal
injury.
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 actuator spring precompression.
D Use lock‐out procedures to be sure that 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 under pressure 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 other hazards that may be present from exposure to process media.
You must remove the actuator from the valve when you install KALREZ packing systems. To allow proper
readjustment of the Vee‐Ball, eccentric disc, or valve disc position, it is recommended that you remove the valve from
the pipeline. Refer to appropriate valve and actuator instruction manuals.
WARNING
Avoid personal injury or equipment damage from uncontrolled movement of parts. If a spring‐return actuator is used, be
sure the actuator spring is resting on its travel stop. If something is obstructing shaft rotation, it is possible that
disconnecting the shaft connector will allow the spring to force the actuator to the end of its rotation. Refer to the
appropriate valve and actuator instruction manuals to remove the actuator.
