The disclosure is directed to a flapper system and a flapper system kit that is compatible with both 2″ and 3″ flush valve seats. In some embodiments, the flapper system is configured to enable a user to select either a 2″ or 3″ flush valve seal for the flapper system. In some embodiments, the flapper system includes a pivot that enables sealing of a flat flush valve seat or an angled flush valve seat. In some embodiments, the flapper system includes one or more adjustable window assemblies that control a fluid flowrate within an internal portion of the flapper system to control buoyancy. In some embodiments, the flapper system includes an adaptor that converts a 2″ valve into a 3″ valve.

An irrigation valve comprises a valve housing made from a valve body joined to a valve bonnet by a plurality of attachment screws. The valve body and valve bonnet have an alignment rib received in an alignment notch when the body and bonnet are joined together such that the holes that receive the attachment screws are automatically aligned with one another. The attachment screws have a smooth portion adjacent a threaded portion such that the smooth portion when visible signals to the user that the attachment screws are clear of the valve body but are still captured in the valve bonnet. The valve includes a solenoid that may be remotely actuated to open the valve. An L-shaped actuator arm is also operatively connected to the solenoid for manually opening the valve with the upper portion of the actuator arm being closer to the user than in previous valves and thus easier to grip and turn. Finally, a metering pin in the valve has a flexible mounting which permits side-to-side motion in a metering hole in the valve member to allow the valve to be self cleaning.

A mechanical pressure gauge indicator for showing a position of a multi-turn non-rising water valve stem is disclosed. The mechanical pressure gauge indicator uses 180 degrees of turning motion to indicate various approximations of pressure downstream of the regulating valve. One half turn of the mechanical simulated pressure gauge indicator indicates ten turns of the multi-turn non-rising water valve stem.

An enclosure for housing electronic controls and devices that provides exceptional access to all sides of the enclosure and is both secure and aesthetically pleasing. The enclosure has a frame, semi-cylindrical doors, a top assembly, and a mounting base. Each of the doors has a door retaining member on its inner lower surfaces which engages and is supported by a receiving member mounted to a lower portion of the frame. The doors may be pivoted open and closed about the retaining and receiving members or may be completely removed from the base by simply lifting the doors off of the frame. Removal of the doors allows unobstructed access to the interior of the enclosure. The top assembly mounts on top of the frame and moves between a closed position and an open position. The top assembly includes a rim which overlaps and engages the top surfaces of the doors to securely retain the doors in the closed position. An opening and closing system mounted on the frame supports the top assembly in the open position. The enclosure is further provided with a lock to secure the top and doors in the closed position and prevent tampering by unauthorized persons.
