2 Safety

Unsafe practices and other important information are emphasised in this manual.

Warnings are emphasised by means of special signs.

2.1 Important information

Always read the manual before using the valve!

WARNING

Indicates that special procedures must be followed to avoid serious personal injury.

CAUTION

Indicates that special procedures must be followed to avoid damage to the valve.

NOTE

Indicates important information to simplify or clarify procedures.

2.2 Warning signs

General warning !

Caustic agents

Danger of injury: (an extra yellow label marked on the actuator from June 2016)

Do NOT attempt to cut the actuator open due to spring under load.

(The lock wire opening is locked). SPRING UNDER LOAD

Do not attempt to cut open

Danger of injury (lasermarked on the actuator)

Do NOT attempt to disassemble the actuator due to spring under load danger!

(The lock wire opening is locked) DO NOT DISASSEMBLE

2Safety

All warnings in this manual are summarised on this page.

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

2.3 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 10 bar product pressure, Alfa Laval recommends NOT to exceed

3barsupporta

ir on the spring side in all the Unique SSV actuators.

If support air is connected always use the 3 bar air relief fittings = 9611995903.

Using the 3 bar air relief fitting also extends the service life of the actuator piston o-ring.

2200-0168_1

Ø26 (Ø1”)

Pos. no. 5

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 = 30 Nm

Ø19 (Ø3/4”)

2200-0169_1

Pos. no. 5

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 = 15 Nm

TD 461-990_2

Alfa Laval recommends max. 3 bar support air

Always use the “3 bar air relief fittings” on support air.
