2 Safety

All warnings in the manual are summarized on this page.

Pay special attention to the instructions below so that severe personal injury and/or damage to the valve are avoided.

2.3 Safety precautions

If support air is utilised:

- Shock in the actuator must N

occur

- Support air on high pressure actuator versions is N

allowed

To prevent shock in the actuator and to prevent exceeding 145 PSI (10 bar) product pressure, Alfa Laval recommends N

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

2200-0168_1

Ø26 (Ø1”)

For actuators, manufactured year 2005-2018, with serial number from 1000000 - 5999999

and from 20000000000 - 59999999999 always use steel adapter (pos 5) = 9614065301

Tighten torque = 23 Ibf-ft (30 Nm)

Ø19 (Ø3/4”)

2200-0169_1

For actuators, manufactured year 2019 --> with serial number from 6000000 to 7000000 and

from 60000000000 to 70000000000 always use steel adapter (pos 5) = 9615374701

Tighten torque = 11 Ibf-ft (15 Nm)

TD 461-990_2

Alfa Laval recommends max. 43,5 PSI (3 bar) support air

Always use the 43,5 PSI (3 bar) air relief fittings” on support air.

Alfa Laval article number = 9611996094 (1/4” = 6,35 mm hose)
