Application:
Any devices or machines with water connection. For direct mounting of solenoid valve in
pipelines.
Mode of action:
If a water  lm of more than 0.5 mm occurs at the water sensor the control unit automati-
cally gives an acoustic alarm and switches the solenoid valve and the device connected
to the control unit off.
Solenoid valve:
Brass solenoid valve, energy-saving circuitry for hand installation (½” with ¾” glanding
- suitable for any ½” tap or ½” tube) or with ½”, ¾” or 1” internal thread on both sides
for line installation. De-energised when closed, for pressure loads from 0.5 ... 10 bar.
Servo-controlled, i.e. free water outlet has to be provided resp. infeed pressure has to
exceed outfeed pressure by 0.5 bar (solenoid not suitable for closed circuits such as
heating systems).
Speci cations:
Power supply: 220 / 240 V 50 / 60 Hz (control unit)
Power consumption:
approx. 2,5 Watt (control unit, approx. 6 W incl. solenoid valve)
Control output: via power socket of safety plug adapter
max. switching current: max. 16 A (ohmic load)
Water sensor: Highly sensitive, plug-in water sensor, 2 m of cable, alarm
triggered as of ½ mm water  lm. Simultaneous plug in of
several water sensors via socket-outlet adaptor GAZ1.
Plug-in extension cable (2 m, 5 m or 10 m long) available.
Solenoid valve: Hence, valve operable in permanent mode; due to energy-
saving circuit valve will not run hot even without cooling
agent.
Valve permanently  xed to control device (approx. 1 m of
connecting cable). Valve body can be removed from coil after
loosening of one nut.
