Functional principle
When the pilot valve is activated, the angle valve is closed by the pressure spring. The position indicator is invisible.
When the pilot valve is deactivated, the angle valve is opened by the pneumatic actuator. The green position indicator becomes visible.
The final positions can be polled by the electrical position indicator.

Installation
Vacuum Connection
Skilled personnel
The vacuum connection may only be established by persons who have suitable technical training and the necessary experience or who have been instructed by the end-user of the product.
DANGER
Caution: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process gases can result if clamps are opened while the vacuum system is pressurized.
Do not open any clamps while the vacuum system is pressurized. Use the type clamps which are suited to overpressure.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with one's bare hands increases the desorption rate.
Always wear clean, lint-free gloves and use clean tools when working in this area.
Caution
Caution: vacuum component
Dirt and damages impair the function of the vacuum component.
When handling vacuum components, take appropriate measures to ensure cleanliness and prevent damages.
Caution
Keep the protective lids and put them in place again when removing the product from the vacuum system.
Remove the protective lids and install the valve to the vacuum system by means of the small flange fittings.
Any installation angle and flow direction may be chosen.

Compressed Air Connection
Skilled personnel
The compressed air connection may only be established by persons who have suitable technical training and the necessary experience or who have been instructed by the end-user of the product.
Caution
Specifications for the plastic tube:
ø4 mm, ø6 mm or ø¼“
bursting pressure 10 bar overpressure (1 MPa)
material: PA soft or PU.
Caution
The compressed air must meet the following specifications:
free of particles >5 µm
DN 16 and DN 25: 3 … 5 bar overpressure DN 40: 3 … 6 bar overpressure
dry, free of oil or containing oil (keep using the same quality).
If compressed air containing oil is used, dispose of the exhaust compressed air outlet in accordance with the relevant regulations.
Caution
To ensure leak tightness of the instant push-in fitting
cut the plastic tube square
make sure the outside of the plastic tube is not damaged.
Caution
Caution: plastic thread
The plastic thread is damaged by tilting or overturning the instant push-in fitting.
use the enclosed instant push-in fitting (with extra-long thread) only.
screw in the instant push-in fitting without tilting it and without exceeding the tightening torque of 0.5 Nm.
Compressed Air Inlet
Caution
Contrary to the illustration below, the compressed air inlets and outlets of the following angle valves are reversed in position:
Vacuum connection DN 40 ISO-KF and serial number (F-No) from
101 for valve with aluminum housing
118 for valve with stainless steel housing
If you wish to connect a ø6 mm, or ø¼“ plastic tube, exchange the instant push-in fitting.

Electrical Connection
Skilled personnel
The electrical connection, in accordance with the VDE 0100 guidelines, may be made only by a licensed electrician, qualified as per VDE 0105. The line cables shall be isolated from the line supply during all electrical work.
WARNING
Caution: mains voltage
The pilot valve can get destroyed if a wrong mains voltage is applied.
The local mains power rating must correspond with the nominal voltage of the pilot valve (see product nameplate). If they do not correspond, exchange the pilot valve ( Furter information).
Caution
The cable must meet the following specifications:
flexible
conductor cross-section 0.75 mm2
cable diameter 10 mm
6-pole without protective conductor or
7-pole with protective conductor.
Preparing the connector
Slide the screw fitting, connector housing, and strain relief on the cable.
