摘要： A fluid valve including a valve body, a flow control member and a cavitation prevention assembly. The valve body has an inlet, an outlet, a fluid passage communicating fluid therebetween, and means for selectively opening and closing fluid communication between the inlet and the outlet. The flow control member is positioned within the fluid passage and has a central passage through which the fluid advances. The cavitation prevention assembly is positioned within the flow passage and is in flow communication with the inlet and the flow control member. The cavitation prevention assembly controls the pressure of the fluid entering the central passage to a level which is sufficiently low to prevent cavitation of the fluid.

摘要： A regulator valve for managing a fluid in an appliance is provided. The regulator valve comprises a housing having an inlet and an outlet, a filter, a pressure regulator, a solenoid valve, a mounting structure, and a locking tab depending from the mounting structure. The inlet and outlet utilize quick connect adaptors. The pressure regulator maintains the fluid in the housing within a desired pressure range and the solenoid valve alternatively permits and prevents expulsion of the fluid from the outlet. The twist mount is inserted through a twist mount aperture on, e.g., a drinking fountain and rotated until a portion of the twist mount engages with a portion of the drinking fountain and the locking tab rests in a tab aperture on the drinking fountain. Therefore, the regulator valve is secured to the drinking fountain and can clean, regulate, and manage the fluid.
