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.
7.2 Before installation
• The angle seat 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
NOTE!
For valves with installed control:
When welding the valve body into the pipeline, the control must
not be installed.
▶Remove control from the actuator (see installation chapter in the
operating instructions for the corresponding control).
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.

WARNING!
Risk of injury from improper assembly!
Assembly with unsuitable tools or non-observance of the tight-
ening torque is dangerous as the device may be damaged.
▶For installation use an open-end wrench, never a pipe wrench.
▶Observe the tightening torque (see “Tab. 5: Tightening torques
of valve body / nipples”).
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 angle seat valve.
7.3.1 Installation of the valve body

7.3.4 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 (see
“Fig. 5”).
→Rotate counter-clockwise (as seen from below) to bring the
actuator module into the required position.
Open-end wrench

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.

Installation
WARNING!
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 “7.3.4
Rotating the actuator”.
Control functions A and B:
→Connect the control medium to the pilot air port 1 of the actuator
(see “Fig. 6”).
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 (see
“Fig. 6”).
If used in an aggressive environment, we recommend con-
veying all free pneumatic connections into a neutral atmo-
sphere 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.
