aIntenance
Internal valve components are subject to normal
deterioration and must be inspect and replaced as
required. The necessity of inspections and replacement
of parts will depend on the severity of service conditions.
Inspections and maintenance must be carried out on a
regularly scheduled basis.
To ensure the safety of personnel and to protect against
property damage, the following steps should be carried
out before beginning disassembly.
1. To prevent the valve from opening suddenly,
disconnect any operating lines to the actuator.
This would include air pressure, electrical power
or control signal lines.
2. Isolate the valve by using the bypass valve or
by shutting down the process completely
Relieve the pressure and drain the process fluid
from both sides of the valve.
3. Relive the pressure contained in the actuator
by venting the actuator loading pressure and
relieving any power actuator spring compre-
ssion.
4. Lock-out procedures should be strictly ad-
hered to while the equipment is being ser-
viced.
5. The Mark HPX Series use spiral-wound gas
kets that are compressed to provide
their seal. Spiral-wound gaskets are
designed for single service, and if they are
disturbed they must be replaced upon reas-
sembly. Used spiral-wound will not seal prop-
erly within the assembly.
