Comes with spring and diaphragm assembly
Valve won’t shut off completely. Sprinklers “weep.”
Loosen solenoid 1 ⁄2 turn and then tighten the solenoid completely (1 ⁄4 turn beyond hand tight). Use the solenoid handle, which is specifically designed to shut the valve off completely and keep it from “weeping.” Also, tighten the bleed screw and bonnet.
Use the external bleed screw to flush the valve. If performance does not improve, turn off the water. Unscrew the bonnet and remove it. Remove the diaphragm and clean it in clear water. Reinstall diaphragm and bonnet. If necessary, replace the diaphragm with kit number 231771.
Valve won’t open
Check water source, controller power, and flow control to make sure they are open.
Turn off water. Unscrew the bonnet and remove it. Inspect body for debris. If a filter is missing from the diaphragm, replace the diaphragm with kit number 231771.
Turn off water. Remove solenoid and replace with a known working solenoid. If the valve still won’t open, replace the solenoid.
