Installation WARNING ® When installing a Swagelok self-venting regulator, position the vent connection or line away from operating personnel. Operating personnel must protect themselves from exposure to system fluids. CAUTION Do not use the regulators as a shutoff device. CAUTION... - Page 5 The best results will be achieved by allowing a small flow to continuously pass through the pilot regulator. This flow can either be vented or, in gas systems, fed back through an orifice into the downstream piping. This is usually referred to as “dynamic regulation”. CAUTION It is not recommended to place a gauge on the dome to set or check the outlet pressure.
- Page 6 This can be achieved by sensing the outlet pressure downstream of the regulator and feeding it back to the regulator. For this purpose Swagelok has provided a special connection, marked on the regulator itself as "P2 feedback".

Page 8: Maintenance
Points of attention before assembly All parts must be clean and undamaged before starting assembly. Swagelok recommends replacing all o-rings and the diaphragm before assembly. All threaded parts must be lightly lubricated before assembly to avoid galling of threads. All o-rings need to be lightly lubricated to improve the lifetime of the o-ring and the performance of the regulator. -
Page 9: Testing
Testing Check the regulator for leakage across the seat, with low- and high inlet pressure. Check the regulator for leakage across the diaphragm, with low- and high outlet pressure. A well performing RD(H)F40 is 100 % bubble tight. If there is a leakage across the seat or the diaphragm, the damaged parts must be replaced. Troubleshooting Problem: The outlet pressure creeps up, without increasing the dome pressure. - Page 10 Warranty Information Swagelok products are backed by The Swagelok Limited Lifetime Warranty.
