About This Product
3/2 shut-off valves, 3/2-way valves and NL filling valves
are components of maintenance units.
3/2 shut-off valves are used to mechanically,
pneumatically and electrically block the compressed air.
3/2-way valves, which make it possible to electrically
switch the compressed air, can be adapted to meet
various requirements through the use of solenoids and
plates.
Filling valves allow a controlled application of the
compressed air to the system.

Assembly, Commissioning,
Operation
Danger of injury if assembled under pressure or
voltage!
Assembling when under pressure or electrical voltage
can lead to injuries and damage to the product or
system components.
O Make sure that the relevant system part is not under
voltage or pressure before you assemble the
product.
O Protect the system against being switched on.

3/2-way valve and BAV 3/2 shut-off
valve
3/2-way valves and 3/2 shut-off valves produce
loud exhaust noises without silencers.
O Only operate 3/2-way valves and 3/2 shut-off
valves with silencers.
BAV 3/2 shut-off valve –
1
mechanically operated*
Adjusting the valve settings (I-III)
The 3/2 shut-off valve is open in position (a).
O To shut off pressure, turn the knob 90° clockwise.
The P1 (2-3) pressure is shut off in position (b) and
P2 pressure is exhausted via output 3.
Locking the valve (I-IV)
To prevent an unauthorized opening of the 3/2 shut-off
valve, the knob can be secured with a padlock.
SOV 3/2-way valve – pneumatically
2
operated*
Setting up connections
1. In connection (a), mount a fitting with thread G 1/8.
2. Connect the pressure supply (d) for the control
pressure.
Function:
W
When applying control pressure, > 2.5 bar switches the
valve to connect 1-2.
W
When releasing compressed air, P1 will be blocked and
pressure P2 exhausted.
The control pressure depends on the working
pressure P1 (see online catalog
www.aventics.com/pneumatics-catalog).
SOV 3/2-way valve – electrically
operated*

Assembling electrical connector with form C
fitting
1. Place the seal (b) on the push-in fitting, form C.
2. Mount the electrical connector (c) and tighten it.
Function:
W
When applying voltage to the solenoid and pressure to
P1 (electric: 2.5 bar < P1 < 10 bar, pneumatic:
2.5 bar < P1 < 16 bar), the valve switches to connect 1-
2.
