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/dome facing 
upwards per Fig 3. 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. 

 

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. 

This regulator can be bottom mounted or panel mounted. The panel mounting kit can be ordered 
separately. 

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.
