Testing
Swagelok recommends that the regulator be tested for seat and shell leakage to atmosphere. A well
performing regulator will not show any indication of leaking. If any evidence of a leak is identified this must be
rectified. Any damaged components must be replaced.
Seat Leak Test
1. Ensure there is sufficient supply pressure to the regulator to be able to perform the tests.
2. Ensure the handle is screwed fully counterclockwise.
3. Maintain an inlet pressure of approximately 14.5 psig (1 bar) on the regulator and close the downstream
shutoff valve.
4. Monitor the outlet pressure. An increase in pressure over time indicates a seat leak.
5. Repeat the procedure with the highest inlet pressure applicable for the regulator and system.
Shell Leak Test
1. Maintain an inlet pressure of approximately 29 psig (2 bar) on the regulator and close the downstream
shutoff valve.
2. Increase the outlet pressure to approximately 14.5 psig (1 bar).
3. Using liquid leak detector, check for bubbles at the spring housing to body interface and the spring
housing weep hole.
4. Repeat the procedure with the highest inlet and outlet pressure applicable for the regulator and system.
