Installation
CAUTION
Do not use the regulator as a shutoff device. A level of leakage across the regulator seat can
occur during normal operation.
Points of Attention Before Installation
This regulator can be equipped with a variety of different options. Before installing the regulator you should
fully understand the functions of the supplied options and the suitability of your particular regulator for the
intended application.
-
The preferred mounting position of the regulator is horizontal with the spring housing facing upwards per
Fig 2. Alternative mounting positions may increase the risk of component wear.
- It may be necessary to remove the regulator from the system during maintenance or service. Ensure that
this is possible.
- The regulator is suitable for gases or liquids. Ensure compatibility between the regulator
’s materials of
construction and the system media.
- Swagelok recommends the use of a non-venting regulator when the process media is hazardous or toxic.
Installation
- Verify that the regulator, its connections, and any accessories are undamaged.
- Verify that the regulator and any accessories are suitable for the system operating pressure and
temperature and have suitable connections.
- At the time of delivery any gauge ports may be plugged with blind fittings. Remove these and connect
gauges if desired.
- If inlet/outlet fittings are being used, assemble them to the regulator
, per the manufacturer’s instructions,
prior to installing the regulator in the system.
CAUTION
Ensure all upstream tubing/pipework is clean and free from debris. Any swarf, lint, wire, etc.,
may damage the regulator, resulting in a seat leak.
- Verify the flow direction of the system and mount the regulator accordingly.
- The RS(H)4 series regulators can be panel mounted.
- Securely make the appropriate connections to the regulator in accordance with the procedures
recommended by the connection manufacturer.
- Ensure that the tubing/pipework and the regulator are adequately supported and that there is no stress on
the connections.
- Upstream and downstream shutoff valves should be installed in the system to facilitate servicing,
maintenance, and troubleshooting of the regulator.
CAUTION
Do not plug the vent port in the spring housing. This would alter the regulator set pressure. The
port must be open to atmosphere either directly or via to a vent line.
CAUTION
Do not plug the vent port in the body plate if the regulator is self-venting. Vented pressure
would become trapped in the regulator. This would alter the regulator set pressure and could be
released upon disassembly. The port must be open to atmosphere either directly or via a vent
line.
