General hazardous situations.
To prevent injury, ensure that:
• The solenoid valve Type 6012 is not to be used in areas where there
is a risk of explosion.
• Do not supply the medium connectors of the system with aggressive
or flammable mediums.
• Do not put any loads on the body (e.g. by placing objects on it or
standing on it).
• Do not make any external modifications to the device bodies. Do not
paint the body parts or screws.
• Installation and repair work may be carried out by authorized technicians 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.
• The device may be operated only when in perfect condition and in
consideration of the operating instructions.
• The general rules of technology apply to application planning and
operation of the device.
5. SYSTEM DESCRIPTION
5.1. General description
The direct-acting solenoid valve Type 6012 is available in two
designs.
Type 6012 is used for the blocking, dosing, filling
and venting of neutral gaseous and liquid media,
in particular for controlling single-acting pneumatic actuators or technical vacuum. The modular
designed valve can be installed individually or in a
block on the multiple manifold.
Type 6012P is used as a special pilot valve for
direct installation on the externally controlled
pneumatic actuators. It consists of the magnetic
actuator Type 6012 and a special connection
body with hollow screw which can be connected
directly to the control air connection of the
actuator. The valve features manual actuation as
standard.
