Safety precautions
Actuators
If support air is utilised:
!
- Shock in the actuator must NEVER occur
- Support air on high pressure actuator versions is NOT allowed
To prevent shock in the actuator and to prevent exceeding 145 PSI (10 bar) product pressure, Alfa Laval recommends NOT
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
