Abstract: A three button programmable sprinkler control system includes a control module having an LCD display, a decrement button, an increment button, and a set or select button. In a preferred embodiment, the control module is battery powered, sized for hand holding, and conveniently positionable in and removable from a system cabinet having therein a power transformer and base triac board including a base set of zone valve triacs. The system cabinet is sized to receive an expansion board having a second group of triacs for expanding the number of sprinkler valves which can be controlled. The control module includes a processor having stored therein a control program which is menu based and which is accessed for setting irrigation control parameters by operation of the three switches with reference to icons displayed for the various menus. The control module interfaces with the base triac board and an expansion board by a connector.

Abstract: A pressure-regulating valve system includes a valve body assembly having inlet, outlet and control chambers. A flow valve assembly includes a diaphragm gasket which movably mounts a valve member. The valve member is movable between a closed position, a full flow open position and two pressure-regulating positions intermediate its closed and full flow positions. A full flow bypass valve assembly selectively communicates the control chamber and the outlet chamber for relieving the fluid pressure in the control chamber whereby the flow valve moves to its full flow open position communicating the inlet and outlet chambers. A pressure regulating subsystem includes multiple pressure regulating modules each having a solenoid-actuated valve and a pressure adjustable valve. The pressure regulating modules are connected in parallel relationship to inlet and outlet manifolds which fluidically communicate with the control and outlet chambers respectively.

Abstract: A connecting device includes a body with an open end, a closed end and a body bore extending therebetween. A core includes an open end, a closed end and a core bore extending therebetween. The body bore is partly filled with potting compound in proximity to its closed end. The device has a closed position with the core inserted into the body bore and the core open end embedded in the potting compound to form a hermetically sealed pocket in the core bore. The body closed end has wire passages which receive wires therethrough. The wires are electrically connected in the sealed pocket. A method of connecting wires includes the steps of providing a body, providing a core telescopically receivable in the body, partly filling the body with potting compound, extending wires into the body and through the potting compound, connecting the wires, inserting the core into the body over the connected wires and forming a hermetically sealed pocket in the core bore.
