ABSTRACT:
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.
