O
O
T
T
to
exceed 3 bar/43.5 PSI support air on the spring side in all the Unique SSV actuators.
If support air is connected always use the 3 bar/43.5 PSI air relief fittings = 9611995903.
Using the air relief fitting also extends the service life of the actuator piston o-ring.

Ideally, as a guide Alfa Laval recommend:
- Store supplied product as supplied in original packaging
- Port opening should be protected against any ingress
- Bare steel (not stainless) should be lightly oiled/greased
- Store in a clean, dry place without direct sunlight or UV light
- Temperature range -5 to 40°C
- Relative humidity less than 60%
- No exposure to corrosive substances (also air contained).
