A sprinkler valve wiring apparatus and method are provided. An irrigation system has a plurality of valves designed to be electrically activated by a control unit. Valve wires extend from the valves to a junction unit. Control unit wires extend from the control unit to the junction unit, and are electrically coupled to the valve wires within the junction unit. The control unit wires include a common wire and a plurality of hot wires. Each hot wire is coupled to a corresponding valve, while the common wire is coupled to all of the valves by the junction unit. The junction unit utilizes resilient blocking members with frangible portions that block unused wire receptacles and can be removed to provide watertight access to the remaining wire receptacles. The junction unit is fixed in place via an anchoring mechanism such as a pipe clip or stake.

Sprinkler valve wiring apparatus and method

A sprinkler valving apparatus and method are provided. An irrigation system has a plurality of valves designed to be electrically activated by a control unit. Each valve may have a first diaphragm that is flexible to control irrigation water flow through the valve. Each of the valves may have a solenoid isolated from irrigation water within the valve by a second diaphragm. The first and second diaphragms are separated by an interior divider with an orifice that can be blocked or unblocked via flexure of the second diaphragm to trigger motion of the first diaphragm. The second diaphragm is actuated by a magnetically actuatable plunger of the solenoid, which extends through an aperture of an interior retainer to reach the second diaphragm. The second diaphragm has a peripheral ring to ensure that it is movable even when negative outlet pressure is applied to the valve.
