MaIntenance

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.
