Different actuator types for the SSV valve
In June 2016 the below change was implemented and the “removable yoke with bolts” version is thereby phased out and
replaced by the “yoke without bolts” version.
NOTE
It is important to check for warnings marked on the actuator when servicing an actuator - see below table.

All warnings in the 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.
Use the “3 bar air relief fitting” = 9611995903
Using the “3 bar air relief fitting” also extends the service life of the actuator piston O-ring.
If support air is connected then the following must be done:
- Always use the steel adapter (pos. 5) = 9614065301
Tighten torque 30 Nm
- Always use the 3 bar air relief fittings = 9611995903
5
Alfa Laval recommends max. 3 bar support air
Always use the “3 bar air relief fittings” on support air.

Recycling information
• Unpacking
-
Packing material consists of wood, plastics, cardboard boxes and in some cases metal straps
Wood and cardboard boxes can be reused, recycled or used for energy recovery
Plastics should be recycled or burnt at a licensed waste incineration plant
Metal straps should be sent for material recycling
• Maintenance
-
During maintenance, oil and wearing parts in the machine are replaced
All metal parts should be sent for material recycling
Worn out or defective electronic parts should be sent to a licensed handler for material recycling
Oil and all non-metal wearing parts must be disposed of in accordance with local regulations
• Scrapping
-
At end of use, the equipment must be recycled in accordance with the relevant local regulations. Besides the equipment
itself, any hazardous residues from the process liquid must be considered and dealt with in a proper manner. When in
doubt, or in the absence of local regulations, please contact your local Alfa Laval sales company. If the actuator is marked
with a danger warning, do not attempt to cut the actuator open.

4.1
Description af valve function
The SSV Two step valve has two pistons inside the actuator, which makes it possible to have an intermediate plug position
where all body ends are open.
SSV Two step valves are made in a Shut-off valve type and a Change – Over valve type.
Step 1a
Type Shut-off valve (only NC)
Two step valves as Shut-off (only as NC) can be used for reducing pressure hammers or dosing e.g. in connection with filling of
a vessel where an exact volume is required.
The degree of opening for the intermediate position can be adjusted by removing spacer rings inside the actuator (see
5.7 Dismantling of (NC) maintainable actuator).

Throttled position can be
adjusted by removing spacers.

Plug seal replacement
Step 1
1. Remove old seal ring using a knife, screwdriver or similar.
Be careful not to damage the plug surface.
If using a screwdriver it must be placed underneath the plug
groove (see drawing 1).
2. Grease the new seal ring with Paralique GTE 703, which is
included in the service kit.
Only use a very small amount of grease.
3. Fit the seal ring on the plug without pressing it into the groove.
Be careful not to twist the seal ring.
Use a screwdriver (two turns) to fit the seal ring properly and to
ensure it is not twisted (see drawing 2).
4. The seal ring can now be mounted by hand or with the Alfa
Laval plug tool.

It is important to place the screwdriver underneath
the plug.

Step 2
Mounting plug seal ring by hand
1. Check the seal ring is premounted as described in step 1.
To ensure correct mounting, press with your thumb on the
seal ring, which must be done approximately 10 times and
always with opposite pressure points, from A to B, to C and
D (see drawing 3).
The rest of the seal ring can now be pressed into the groove
so the whole seal ring is mounted. Check that there are NO
“bulge” (see drawing 4).
If there is a little bulge – then use the screwdriver to eliminate
the bulge.
Again press with the thumb on the seal ring and keep the
pressure while rotating 360° (see drawing 3).
2. It is important to release compressed air behind the seal ring.
This is done with a screwdriver and always underneath the
plug as shown.
It must be done at one or two different points on the
circumference.
Be careful not to make marks on the surface of the plug and
seal ring (see drawing 5).

Exhaust holes
for screwdriver
1. Part B
“Part B” has a small and a large diameter as the tool can be
used for two plug sizes – e.g. plug tool = 9613172902 can be
used for DN50/ISO51 (small) and DN65/ISO63 (large).
“Part B” therefore has to be turned so it matches the plug
size diameter.
2. Part A
“Part A” has an upper and lower exhaust hole, as the tool can
be used for two plug sizes – e.g. plug tool = 9613172902.
The upper exhaust hole is for the small plug size e.g.
DN50/ISO51 (small) and the lower exhaust hole is for
DN65/ISO63 (large).
When using a “change-over plug” the ø20 spindle must also
be fitted in “part A” and “part B” (see drawing 2).
When using a “reverse acting plug” the ø20 spindle must only
be fitted in “part A” (see drawing 2).
When using a “standard shut-off plug” the ø20 spindle is only
fitted in “part B” (see drawing 1).
3. Fit the plug spindle in “part B” or “part A”.
Place “part A” onto “part B” and then press “hard” down on
top of “part A”.
Now fit the screwdriver into the exhaust hole and underneath
the plug groove meanwhile keeping the pressure on “part A”.
This should ensure correct removal of air behind the seal
ring. Normally the sound “Psst” can be heard one time (see
drawing 3).
A “drill press” can of course also be used to press down on
“part A”.
4. It is important to release compressed air behind the seal ring.
This is done with a screwdriver and always underneath the
plug as shown (see drawing 4).

- Always lubricate the spindle and o-rings thoroughly with
“Molykote Longterm 2 Plus” before mounting the new bushings.

Step 2
Introduction - Standard socket wrench
Use a 27 mm socket wrench to mount the bushings, as the space in the yoke is limited.
A socket wrench 24x27 (length = 185 mm) is a standard tool, which can be purchased from all tool shops.
A = 185 mm

Step 3
Introduction - Aligning spindle
The actuator spindle can in some cases be forced off centre by the internal spring, see drawing below.
In these cases, the alignment spindle shown below, together with the socket wrench, is a great help and ensures a reliable
mounting of the bushing. The spindle can either be purchased from Alfa Laval together with the socket wrench (9614-1984-01)
or it can be manufactured locally using the below dimensions.

principle The valve is a pneumatic seat valve in a hygienic and modular design remote-controlled by means of compressed air.
It has few and simple moveable parts which results in a very reliable valve and low maintenance cost.
Standard design The Unique SSV Two Step valve comes in a one or two body configuration. With its module built structure it is
designed for flexibility and easy customization through the electronic configurator.

Max. product pressure
1000 kPa (10 bar).
Min. product pressure
Full vacuum (depending on product specifications).
