B - Bimetallic steam trap
5.5 Installation position
The steam trap can be installed in any position except screw cap/cover (pos. 6) down.
Note installation position relative to flow, see marking on the valve.
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 page 4 - Fig. 12 page 8)
- Depressurise equipment (isolate supply line, also discharge line if there is back pressure).
- Release and dismantle screw cap (pos. 6) and cover screw connection (pos. 28).
- Unscrew bimetallic controller (pos. 24) and remove strainer (pos. 2).
- Clean body (pos. 1), screw cap/cover (pos. 6) and strainer (pos. 2) as well as all seal
faces.
- Clean bimetallic controller (pos. 24) and check sealing components at seat (pos. 24.1). If
the operator thinks there is unwarranted leakage of steam at the steam trap, we
recommend checking the controller setting or replacing the complete bimetallic controller
(pos. 24).
- Insert strainer (pos. 2), making sure the sealing faces are clean.
- Screw in bimetallic controller (pos. 24) and tighten (see 7.3).
- Replace screw cap/cover (pos. 6) and assemble hexagon nuts (pos. 28) (see 7.3).
- If the model has sealing rings (pos. 11) and (pos. 26) they should be replaced.
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 PN 16-40 or
“Rivolta” lubricant and parting agent for PN 63 onwards).
