7. INSTALLATION
7.1. Safety instructions
DANGER!
Risk of injury from high pressure!
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
WARNING!
Risk of injury from improper installation!
• Installation may be carried out by authorized technicians only
and with the appropriate tools!
Risk of injury from unintentional activation of the system and
an uncontrolled restart!
• Secure system from unintentional activation.
• Following installation, ensure a controlled restart.
For control function I – Danger if pilot pressure fails!
For control function I control and resetting occur pneumatically. If
the pressure fails, no defined position is reached.
• To ensure a controlled restart, first pressurize the device with
pilot pressure, then switch on the medium.
Risk of injury from moving parts in the device!
• Do not reach into openings.

• The globe valve can be installed in any installation position, preferably with the actuator face up.
• Before connecting the valve, ensure the lines are flush.
• Observe direction of flow (see type label).
7.2.1. Preparatory work
→ Clean pipelines (sealing material, swarf, etc.).
Devices with welded body
Remove the actuator from the valve body:
→ Clamp the valve body in a holding device.
NOTE!
Damage to the seat seal or the seat contour!
• When removing the actuator, ensure that the valve is in open
position.
→ Control function A pressurize the pilot air port 1 with com-
pressed air (5 bar): valve opens.
→ Using a suitable open-end wrench, place the wrench flat on the
tube.
→ Unscrew the actuator from the valve body.

Type 2101
Installation
Dirt trap for devices with authorization in accordance with DIN
EN 161
In accordance with DIN EN 161 „Automatic shut-off valves for gas
burners and gas appliances“ a dirt trap must be connected upstream
of the valve and prevent the insertion of a 1 mm plug gauge.
→ If the authorisation also applies to stainless steel bodies, the
same type of dirt trap must be attached in front of the globe
valve.
7.3.1. Installation of the valve body
Welded bodies
→ Weld valve body in pipeline system.
Other body versions
→ Connect body to pipeline.
7.3.2. Install actuator (welded body)
Graphite seal
Fig. 3: Graphite seal
→ Check the graphite seal and if required, replace it.
WARNING!
Danger if incorrect lubricants used!
Unsuitable lubricant may contaminate the medium. In oxygen
applications there is a risk of an explosion!
• In specific applications, e.g. oxygen or analysis applications, use
appropriately authorised lubricants only.
→ Grease nipple thread before re-installing the actuator (e.g. with
Klüber paste UH1 96-402 from Klüber).
NOTE!
Damage to the seat seal or the seat contour!
• When installing the actuator, ensure that the valve is in open
position.
→ Control function A pressurize the pilot air port 1 with compressed
air (5 bar): valve opens.
→ Screw actuator into the valve body.
Observe tightening torque “Tab. 1: Temperature ranges Ex
area”).

7.3.3. Rotating the actuator
The position of the connections can be aligned steplessly by rotating
the actuator through 360°.
NOTE!
Damage to the seat seal or the seat contour.
• When rotating the actuator, ensure that the valve is in open
position.
Procedure:
→ Clamp the valve body in a holding device
(applies only to valves which have not yet been installed).
→ Control function A pressurize the pilot air port 1 with com-
pressed air (5 bar): valve opens.
→ Counter on the flats of the nipple with a suitable open-end
wrench.
→ Place suitable open-end wrench on the hexagon of the actuator.
WARNING!
Risk of injury from discharge of medium and pressure.
If the direction of rotation is wrong, the body interface may become
detached.
• Rotate the actuator module in the specified direction only.
→ Actuator with hexagon:
Rotate counter-clockwise (as seen from below) to bring the
actuator module into the required position.

7.4. Pneumatic connection
DANGER!
Danger – high pressure in the equipment.
• Before loosening the lines and valves, turn off the pressure and
vent the lines.
WARNING!
Risk of injury from unsuitable connection hoses.
Hoses which cannot withstand the pressure and temperature range
may result in hazardous situations.
• Use only hoses which are authorised for the indicated pressure
and temperature range.
• Observe the data sheet specifications from the hose manufacturers.
For control function I – Danger if pilot pressure fails.
For control function I control and resetting occur pneumatically. If
the pressure fails, no defined position is reached.
• To ensure a controlled restart, first pressurize the device with
pilot pressure, then switch on the medium.
7.4.1. Connection of the control medium
If the position of the pilot air ports for installation of the
hoses is unfavorable, these can be aligned steplessly by
rotating the actuator through 360°.
The procedure is described in the chapter entitled “7.3.3.
Rotating the actuator”.
Control functions A and B:
→ Connect the control medium to the pilot air port 1 of the
actuator.
Silencer
For the versions with a plug-in connection the silencer for reducing
the exhaust air noise is supplied loose.
→ Plug the silencer into the free air discharge connection 2.
If used in an aggressive environment, we recommend
conveying all free pneumatic connections into a neutral
atmosphere with the aid of a pneumatic hose.
Control function I:
→ Connect the control medium to the pilot air port 1 and 2 of the
actuator (see “Fig. 6”)
Pressure on connection 1 opens the valve.
Pressure on connection 2 closes the valve.
