6.0 Putting the valve into operation
7.0 Care and maintenance
Maintanance and maintenance-intervals have to be defined by the operator according to
the requirements.
7.1 Cleaning / replacing controller assembly
(see Fig. 1- Fig. 2 page 4 and Fig. 3 page 8)
- Remove pipe flange until there is a clearance of roughly 560mm in the pipeline axis to the
left.
- Unscrew hexagon nuts (Pos. 28)
- Pull cover (Pos. 40) away from body until the studs (Pos. 27) no longer protrude into the
cover (Pos. 40). Use lifting gear if necessary.
- Tilt cover (Pos. 40) and controller assy. (Pos. 24) and pull from body (Pos. 1) until
diaphragm capsule (Pos. 24.4) protrudes from body (Pos. 1).
- Raise cover (Pos. 40) and controller assy. (Pos. 24) and withdraw from body (Pos. 1).
- Pull spring clip (Pos. 24.5) off radially and remove diaphragm capsule (Pos. 24.4) from
seat (Pos. 24.1).
- Clean diaphragm capsule (Pos. 24.4) and check sealing components on seat (Pos. 24.1).
If the operator thinks that there is unwarranted leakage at the steam trap we recommend
replacing the diaphragm capsule (Pos. 24.4).
- If the sealing faces at the seat (Pos. 24.1) are damaged, this should also be replaced by a
new component.
- Function test the diaphragm capsule in accordance with 7.
- If the non-return protection (Pos. 57) is faulty, the complete controller (Pos. 24) should be
changed as an assembly.
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50 °C) or low (< 0 °C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
ATTENTION !
- refer to item 10.0 and 11.0 prior to dismantling and repair work!
- refer to item 6.0 before restarting the plant !
Prior to installation, threads and seal faces should be coated with temperature-
stable lubricant (e.g. “OKS Anti-Seize Paste” white/metal-free for PN16-40 or
“Rivolta” lubricant and parting agent silver for PN63 onwards).
