to exceed 43.5 PSI (3 bar) support air on the spring side in all the Unique SSV actuators.
If support air is connected always u se the 43 PSI (3 bar) air relief fittings = 9611996094 (1/4” = 6,35 mm hose)
Using the 43.5 PSI (3 bar) air relief fitting also extends the service life of the actuator piston o -ring.
Obs. if using a 6 mm hose then use air relief fittings = 9611995903
