Installation
Leave the blue foil on the valve body openings as long as possible in order to protect the valve interior from dust and
particles. The valve and seals must not be cleaned before installation. The valve is assembled at VAT in a clean
environment and sealed in a plastic bag.
Attach the valve to a clean system only. The screws on the flanges have to be tightened uniformly in crosswise order.
Connect compressed air and electrical power only if
valve is installed into the vacuum system
moving parts cannot be touched
Do not touch electrical parts under voltage.
Admissible forces
The dimensions and tolerances specified on the dimensional drawing must be met under all operating conditions.
Compressed air connection
Compressed air pressure
(min. - max. overpressure) :
4 - 7 bar / 55 - 95 psi
Use only clean, dry or slightly oiled air.
Connections:
internal threads Rp 1/8“ (for USA : 1/8“ NPT)
with solenoid : connection „P“ for air supply
connection „R“ for exhaust
without solenoid : connections „open“ and „closed“
Electrical connection
Sockets for position indicator and solenoid are supplied with the valve. Verify that control voltage matches voltage indicated
on the solenoid.
Wiring diagrams :
Solenoid for impulse actuation
Position indicator „open/close“
(Standard)
Position indicator 1xLo / 2xLg
