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 use 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

*) Careful if using support air on spring side and a high product
pressure above the plug, as this can result in a high “hammer
effect” which can damage the actuator.
Use Alfa Laval part no. 9611996094, which ensures max. 43,5
PSI (3 bar) support air pressure.
Alternatively remove the product pressure while activating the
plug.
