2.3. Safety precautions
Installation:
Before installing always read the technical data thoroughly (see chapter 6 Technical data)
Never install the valve with connected compressed air
With a connected airline there is a chance that the actuator will be activated
during installation and risk of injury.
During operation:
Never touch the valve or the pipes while processing hot liquids.
Never put your hands under or near the outlet during operation,
there is a risk of injury if the product consists of aggressive or hot liquid.
Never remove the air line during operation, if a loose airline is activated,
there is a risk of injury from a swishing line.
Performing maintenance:
Before starting maintenance, check that the valve with pipe lines are still hot.
Do not perform any maintenance on the hot valve.
Before starting , maintenance, disconnect compressed air line.
If present, disconnect wiring from status report.
Never pressurize the valve when servicing the valve.
Always apply the seals correctly and with care.
The warranty for TMG Holland products depends on the use of original TMG Holland
spare parts.
During transport:
Always ensure that all connections are removed before you remove the valve from
the installation.
Check the weight of the valve before removing it from the installation.
Always ensure that the valve is properly secured during transport if specially
designed packaging material is available, it must be used.
Residual fluid that flows out of valve and pipe lines can contain acid or lye.
Dispose of spilled liquid according to the rules.

3 Installation
The instruction manual is part of the delivery.
Study the instructions carefully.
3.1. Unpacking / intermediate storage
Check the delivery for:
1. Complete valve
2. Instruction manual
3. Valve for damage
4. Delivery note
Step 1
Remove packaging material
Use the right tools to remove staples and / or straps.
Step 2
Please note weight of the valve
Carefully lift the valve out of the package, use lifting equipment if necessary.
Step 3
Remove possible packing materials from the valve ports.
Step 4
Inspect the valve for any transport damage.
3.2. Disassembly
The valve is assembled complete.
When the body of the valve is equipped with welding
connections, the valve will have to be disassembled first.
Please observe the following steps.
Place the valve vertically and remove the Try-clamp
Never weld the Valve Body with an Actuator mounted
Carefully lift the actuator with the Cone and Bellows (CBS).
Be careful not to damage O-ring and Bellows.
Place the Actuator with CBS in a safe place.
The Body can now be mounted in pipework.

4 Install and operation
4.1 Required tools
-Wrench 14 mm
-Wrench 19 mm
-O-ring remover
-Spring Tensioner
-Grease for threaded ends ; Never Seize pasta - Weicon ASW 040 P or equal
-Grease for cylinder surface; Teflon cylinder grease - Magnalube G MGL 4 or equal
-Lubricant for O-rings, make sure it is allowed in the food industrie.
4.2 Welding instructions
The valve body can be equipped with a welding end.
Always disassemble the complete valve before welding.
The weld ends are not equipped with weld edge chamfer.
Body and ferrule must be welded into the
pipe system according to ISO 3834 certification.
When the Body is installed, the Actuator can be mounted with the CBS. Make sure that the O-ring is
properly mounted on the CBS. Place the actuator with CBS on the body.
Secure Actuator to CBS with Try-Clamp.
The Actuator for the Reducing valve is applied as
SA type, which means that the Actuator will lift the
Cone in rest position.
The closing force of the Cone can be adjusted by
means of a variable air pressure.
Experimentally, it can be set at which pressure
of the medium the cone will lift.
Air pressure can be connected to connection P1 (G1/8")
A air vent is mounted on P2.

10
4.3 Mounting the CBS
For mounting the CBS it is recommended to clamp the CBS in a vice. The vise must be fitted with soft
blocks to prevent damage to the Cone
To mount the CBS, the actuator will have to be actuated with low air pressure to P1, which
creates space between the adapter (170) and the CBS plate (190).
In this way the CBS can be mounted without tension, as shown in figure A
-Clamp the CBS in the vise as shown
-Connect the air supply to the Actuator at P1
-Carefully place the Actuator with the adapter over the stem so that the guide ring in adapter is
not damaged
-Make sure there is a low air pressure on P1
-The Stem (130) is pushed out a bit
-Use a 19 wrench to mount the Stem (130) on the CBS
-When mounting, make sure that the adapter plate does not touch the CBS plate (Figure A) to
avoid tension on the CBS
-Disconnect the air supply and remove the Actuator with CBS from the vise
The Actuator with CBS is now ready to mount in the Body

5 Maintenance
5.1. General maintenance
Recommended spare parts: Maintenance kits (see 6 Technical data)
Order service kits from the service kits section (see 6 Technical data)
Ordering spare parts: Contact the Sales Department.
The Actuator is Spring Loaded,
for disassembly it is necessary
to use a Spring Tensioner.
5.2. Disassembly Cone with Bellows
The Actuator with the Cone and Bellows (CBS) can be disassembled
in the field without disassembling the valve body.
Make sure the air system is turned off.
Remove the air hose from the Actuator.
Remove the Try-clamp
Carefully lift the actuator with CBS.
Be careful not to damage O-ring and Bellows.
Place the Actuator with CBS in a dust-free place
on the workbench in a vice as shown.
Use soft blocks in the vise
to avoid damaging the Cone
Use wrench 19 for disassembly the CBS
and use little compressed air on P1
Follow the CBS assembly guidelines in reverse order
for proper disassembly (chapter 4.3)
Work carefully, the CBS must be
without tension at all times.

12
5.3. Actuator maintenance
Disassembling the Actuator.
Place the Actuator in a vise as shown.
Do not clamp the actuator in the center of the cylinder.
Use soft blocks in the vise to avoid damaging the Actuator.
Install a Spring Tensioner to the bottom of the actuator as shown.
Pull the piston up by turning the
spring tensioner counterclockwise.
Unscrew the Adapter from the
Actuator Body by turning it counterclockwise.
Carefully pull the spring tensioner with
piston and spring out of the Actuator Body.
The spring can then be released by turning
the spring tensioner clockwise.
Remove the spring tensioner by
turning the spindle out of the Stem.
Remove the Actuator Body from the vise
and clean it thoroughly.
Check whether the Air vent nipple is damaged
and can pass enough air.
If damaged, install a new Air Vent.
