Operation of the On/Off Valve and Control Rod
The On/Off Valve and the Control Rod are an important part of the RainTrain2
®
. This section describes the operation of
the On/Off Valve and Control Rod.
The Control Rod will latch in the Off position when the Control Rod Stem is up and pushed to the rear of the machine
(see figure 4). Note: Verify that the Latching Spool on the Control Rod is adjusted correctly. The Latching Pawl should
never fall behind the Latching Spool when the Control Rod is pushed completely into the machine.
In the Off position, the Control Rod unseats the Check Ball Valve and allows water to pass into the outer diaphragm
cavity. This closes the diaphragm and does not allow water to pass through to the turbine or the sprinkler (see figure 4).
