4 About this product

3/2-shut-off valves, 3/2-directional valves and NL filling valves are components of
maintenance units.
3/2-shut-off valves are used to shut off the supply of compressed air mechanically
or pneumatically.
3/2-directional valves that enable electrical switching of compressed air can be
customized to different requirements via various coils and plates.
Filling valves permit controlled application of compressed air on the system.

5 Assembly, commissioning and operation

Danger of fire
Overcurrent, e.g. resulting from a short circuit, can cause overheating and
fires.
Provide for overcurrent protection as per EN 60204-1 if the current in any
u
circuit can exceed either the rated value for a component or the current
carrying capacity of the conductor, whichever is the lower value.

DANGER
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.
1. Make sure that the relevant system component is without pressure and
voltage before you assemble the product.
2. Protect the system against being restarted.
Danger of burns!
The surfaces of adjacent system components can become hot during opera-
tion.
1. Let the system component cool off before disassembling it.
2. Do not touch the device during operation.

5.2 3/2-directional valve SOV and 3/2-shut-off valve BAV

Explosive atmospheres
If unsuitable components are used switching processes may trigger ignition in
explosive areas.
Please only use ATEX-version pilot valves and coils in explosive areas.
u
If silencers are not used, 3/2-directional and 3/2-shut-off valves emit
very loud exhaust noises.
• Please therefore only operate 3/2-directional and 3/2-shut-off
valves with silencers.
