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

3 bar support air 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.

1. Fit o-rings (3, 11) in bonnet (13) and o-ring (3) on cylinder (1).

2. Fit the cylinder.

033_1

Step 3

1. Fit lock wire (12) through the slot in cylinder (1) into the hole in bonnet (13).

2. Rotate the cylinder 360° (see step 4).

099

Rotate by hand or with filter strap!

Step 4

NOTE!

It is recommended to rotate cylinder (1) further 180° in relation to bonnet (13) so that the top and bottom air connections are fixed on the same side.

6 Technical data

It is important to observe the technical data during installation, operation and maintenance.

Inform the personnel about the technical data.

6.1

Technical data

The valve is remote-controlled by means of compressed air or manually operated. The small single seat valve is very reliable due to its simple design and few moving parts.

Standard Design The Small Single Seat Valve comes as a pneumatic or manual operated in either a one or two body configuration.

The plug is a PVDF plug. All components are assembled by means of clamp rings, whereas the piston and valve plug have a threaded connection.
