ABSTRACT:
A timed control valve is of the type that is installed in a fluid line upstream from a regular valve and capable of being physically oriented an any direction in the fluid line. The timed control valve is capable of sensing at least the normal flow of fluid when the regular valve is opened, stopping the normal flow at an end of a first predetermined period of time beginning with an initial sensing of the normal flow; and then allowing the normal flow at an end of a second predetermined period of time beginning with an initial stopping of the normal flow. Various embodiments of the timed control valve include different sensing and timing device for regulating the overall amount of the fluid that can be used and can even be configured to protect against a major loss of fluid if there is a rupture or failure of the fluid line down stream of the timed control valve. The invention also includes the method of doing the same.
