Multifunctional restrictive valve

A valve for controlling the flow of water therethrough, the valve comprising:

• a main body including a channel therethrough, the channel including channel walls, the main body for receiving water at an inlet port and passing water through an outlet port;
• and
• a flow control assembly in operative engagement with the main body, the flow control assembly including a temperature sensor and piston assembly, the temperature sensor and piston assembly including a temperature sensor and a piston, the temperature sensor engaged with the channel walls of the main body, the temperature sensor and piston assembly adapted to substantially block and unblock the flow of water in the channel responsive to the temperature sensor, the flow control assembly further including an override assembly movable between a first and a second position, the second position for enabling the temperature sensor and piston assembly to control the flow of water through the main body, the first position for bypassing the temperature sensor and piston assembly and allowing water to flow, the override assembly further including means to set the override assembly in the second position;
• wherein the override assembly includes a handle to release the override assembly from the second position;
• wherein the means to set the override assembly includes means to automatically set the override assembly to the second position;
• wherein the means to automatically set the override assembly to the second position is responsive to a substantial change in the hydraulic pressure at the inlet port;
• wherein the override assembly and the means to set includes a slide, movable with respect to the channel walls and with respect to the piston, the slide including slide ports therethrough, the slide ports for passing water between the inlet and the outlet ports, the temperature sensor and piston assembly, adapted to move the piston to a slide port blocking position when the temperature sensor expands in response to the water temperature exceeding the predetermined temperature and the override assembly in the second position;
• and
• wherein the slide is adapted to move between the second position wherein the piston is capable of blocking the slide ports and the first position, wherein the piston is no longer capable of blocking the slide ports.
