Maintenance
Handlever parts are subject to normal
wear/corrosion and must be inspected and replaced
when necessary. The frequency of inspection and
replacement depends on the severity of service
conditions.
WARNING
Avoid personal injury or damage to
property from sudden release of
pressure or uncontrolled process fluid.
Before starting disassembly:
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 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
either side of the valve.
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 additional measures
that must be taken to protect against
process media.
