Bauer Rainstar TX Plus Series - 16 Low-Pressure or Underpressure Shut-Off Valve; Ecostar 4300); 17 Low-Pressure or Underpressure Shut-Off Valve (Optional with Mechanical Speed Control)

Operating manual for BAUER RAINSTAR series TX Plus 57
16 LOW-PRESSURE OR UNDERPRESSURE SHUT-OFF VALVE
(OPTIONAL with ECOSTAR 4300)
With the low pressure shut-off valve option, a diaphragm valve is opened quickly at the end of the irrigation run,
releasing a big water stream into the open. This causes sudden pressure decrease in the supply line (to about
half the original pressure). Through this drop in pressure a pressure switch shuts off the pumping unit and thus
also the water supply.
Therefore this valve can only be used in combination with an automatic pump shut-off device.

Before starting up with water again the hand lever of the
three-way cock must be shifted to the START position
(downward) - the shut-off valve is relieved and opens.
