Risk of injury due to malfunction of valves with alternating
current (AC)!
Sticking core causes coil to overheat, resulting in a malfunction.
▶Monitor process to ensure function is in perfect working order!
Risk of short-circuit/escape of media through leaking screw joints!
▶Ensure seals are seated correctly.
▶Carefully screw valve and connection lines together.
General hazardous situations.
To prevent injury, ensure that:
▶Do not make any internal or external changes. Ensure that the system
cannot be activated unintentionally.
▶Installation and repair work may be carried out by authorized techni-
cians only and with the appropriate tools.
▶After an interruption in the power supply or pneumatic supply, ensure
that the process is restarted in a defined or controlled manner.
▶Do not put any loads on the body.
3 BASIC SAFETY INSTRUCTIONS
These safety instructions do not make allowance for any contingencies
and events which may arise during installation, operation and maintenance.
Danger – high pressure!
▶Before loosening the lines and valves, turn off the pressure and
vent the lines.
Risk of electric shock!
▶Before reaching into the system, switch off the power supply and
secure to prevent reactivation!
▶Observe applicable accident prevention and safety regulations for
electrical equipment!
Risk of burns/Risk of fire if used continuously through hot device
surface!
▶Keep the device away from highly flammable substances and media
and do not touch with bare hands.

4 SYSTEM DESCRIPTION
4.1 General description
The solenoid valve modules
(SV modules) are stacked
in blocks with the aid of pull
rods and connection pieces.
The valve has the following
functions:
• Distributor (1 input, 2-10
outputs)
• Collector (1 output, 2-10
inputs)
• mixed (2-10 SV modules)
Collector
Collector
Distributor
Distributor
The SV modules with collector function have a non-return valve con-
nected upstream as standard. As a result, the minimum pressure
difference increases to 1 bar.
