b. If the solenoid does not function with a 9-volt battery, check the battery.
If the problem with the solenoid continues after using a second battery,
it should be replaced.
5. If the valve is weeping or not closing completely,
the adapter being used with the S-305DC solenoid
may be loose, cross-threaded, or missing an O-ring,
the adapter sleeve could be damaged, or the valve
diaphragm inside the valve could be in need of
cleaning or replacement.
6. If the valve is not opening completely, the adapter
being used with the S-305DC solenoid may be too
tight, the adapter sleeve could be damaged, or the
valve water passage down stream may be plugged
and in need of cleaning.
7. Solenoid parts list (see A).
5.3 Troubleshooting Hydraulic Valves
1. Verify that the valve opens and closes. If it does not, the problem is with
the valve.
a. Verify that the static mainline pressure at the valve is below 150 PSI
(10.5 BAR) and above 10 PSI (.7 BAR).
b. Verify that the valve size is correct for the flow rate of the system.
c. The S-305DC solenoid should be installed only on normally closed
2-way valves.
