A valve body including an inlet pipe, an outlet pipe, a valve body, a flow channel formed in the valve body. A valve plug unit has a stem, a wing, and a plug arranged along a longitudinal access of the valve plug unit, the plug being arranged to be rotatable in a plug housing formed in the flow channel. A bypass inlet is arranged in the outlet pipe to facilitate fluid flow to and from the reservoir. A bypass outlet nozzle is arranged in a wall of the chamber, the bypass outlet nozzle configured and arranged such to direct a fluid jet stream at a surface of the wing that is fixedly connected to the stem of the valve plug unit to thereby rotate the wing from a first position to a second position, the bypass outlet nozzle being fluidically connected to the reservoir via a bypass.

A self-energized programmable timer valve is provided in embodiments of this invention that can be used in watering and other systems, such as lawn watering systems and agricultural watering systems. The invention provides one or more components that serve the functions of a clock, a valve and an energizer (e.g., turbine) (i.e., a clock function, a valve function, and an energizing and/or turbine function) to control the flow of media (e.g., water) through the valve.

A normally closed valve according to the invention comprises a closure delay system utilizing the effect of vacuum on a flexible suction cup to generate a force that keeps the valve open when in an open orientation for a preset time period. The valve further comprises a closure delay mechanism including an actuator shaft and a suction cup disposed in a cavity, being configured for downward reciprocating movement, wherein the suction cup engages the cavity top wall when the valve is in closed orientation thereby closing the valve, and adhering to a suction surface of the cavity when the actuator shaft moves under pressure for switching the valve from closed to open orientation thereby opening the valve. The suction cup automatically disengages the suction surface a preset time period after pressure ceases to be applied to the actuator shaft and reengages the cavity top wall thereby closing the valve.
