Abstract: A leak detector assembly for use with a backflow prevention device includes a housing defining a passageway for receiving a fluid. A flap assembly couples to the housing for generating a low flow error signal indicating minimal fluid passing through the passageway and a fully actuated error signal indicating significant fluid passing through the passageway. The flap assembly includes a flap mounted in the passageway such that significant flow of the fluid moves the flap to generate the fully actuated error signal. The flap assembly also includes a sensing element on the flap to determine a presence of the fluid without movement of the flap to generate the low flow error signal based on a low flow of the fluid.

Abstract: A pressure regulator assembly including a regulator valve, a spring guide, a spring extending between the spring guide and regulator valve for setting operation of the regulator valve, a sleeve coupled to the spring guide, a spring cage coupled to the sleeve, an adjustment stem coupled to the sleeve, a dial assembly coupled to the spring cage, and an adjustment cap coupled to the adjustment stem, wherein when the cap is depressed, interaction between the spring cage, spring guide and sleeve causes the spring guide to selectively rotate between a normal mode and a fast-fill mode. In the normal mode, adjustment of the cap determines an output pressure. In the fast-fill mode, the spring is further compressed by movement of the spring guide to a predetermined setting to provide a predetermined output pressure.

Abstract: A snap-fit lever for actuation of a valve assembly has an elongated valve stem with a ball. The snap-fit lever has a handle portion and a seat portion coupled to the handle portion. The seat portion defines an entry, a retention cavity, and a passage from the entry to the retention cavity. The passage guides the ball from the entry to the retention cavity. The snap-fit lever has deflectable fingers protruding from the seat portion to form part of the retention cavity and the passage. The deflectable fingers deflect to allow the ball to move from the passage into the retention cavity and capture the ball. The deflectable fingers enable rotation of the handle portion about a first axis of the elongated valve stem and allow rotation of the handle portion about a second axis perpendicular to the first axis for moving the elongated valve stem into an actuated position.

Abstract: A pressure regulator assembly has a normal mode and a regulated fast-fill mode and includes a spring cage and a body coupled together. The spring cage and body define an inlet in fluid communication with an outlet as well as an interior between the inlet and the outlet. A diaphragm assembly mounts in the interior for selectively closing a flowpath between the inlet and the outlet. A preload spring in the interior applies force on the diaphragm assembly so that in the normal mode, the flowpath is closed if a downstream pressure is above a first pressure. An actuation assembly includes a lever coupled to the spring cage and a push rod mounted so that in the regulated fast-fill mode, the lever slides so that the push rod further compresses the preload spring to open the flowpath and regulate flow therethrough if the downstream pressure is below a second pressure.
