A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

1. 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; anda 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; andwherein 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. 2. The valve of claim 1, wherein the slide includes a slide spring engaging the slide and the channel walls, the slide spring for urging the slide towards the inlet port, and the piston includes a piston spring engaging the piston and the channel walls for urging the piston against the temperature sensor. 3. The valve of claim 1, wherein the slide spring is adapted to allow the slide to move in response to a change in hydraulic pressure. 4. The valve of claim 1, wherein the override assembly is adapted to respond to hydraulic pressure at the inlet port, moving between the first and second positions responsive to changes thereof. 5. A valve for controlling a flow of water, the valve comprising: a main body including a channel extending through the main body, the channel configured to receive water at an inlet port and pass water to an outlet port; anda flow control assembly in operative engagement with the channel, the flow control assembly including: a temperature sensor configured to sense a temperature of water flowing through the channel; anda flow control member configured to substantially block a flow of water in the channel responsive to the temperature sensor, the flow control member movable between a first position and a second position, where in when the flow control member is between the first position and the second position the flow control member is configured to control the flow of water through the channel as a function of the temperature sensor, where in when the flow control member is in the second position water is substantially blocked from flowing in the channel;wherein the flow control assembly is configurable to allow water to flow in the channel regardless of the temperature of water flowing through the channel. 6. The valve as specified in claim 5, wherein the flow control assembly further includes an override member configured to allow water to flow in the channel regardless of the temperature of the water flowing through the channel.
