A digital water timer may include a main body, a water valve, a locating base, a driving base, and a timer. The main body has a water inlet and a water outlet, and a valve tube protrudes from a lateral side of the main body. The water valve connected to the main body is controlled by the timer to achieve on/off operation of channels inside the main body. The locating base is secured on the main body, and the driving base is adapted to have rotation relative to the locating base and be secured at a specific position after rotated. The timer installed in the driving base comprises a display panel and an operation interface which are exposed externally for operation. The driving base with the timer is rotated relative to the locating base, and the display panel is adjusted as needed to provide an optimal view for operation.

A valve device is capable of precisely adjusting a flow rate variation with time, aging, or the like without using an external sensor or using as few external sensors as possible. The apparatus includes an adjusting actuator for adjusting the position of the operating member positioned at the open position, a communication unit for receiving adjustment information relating to the adjustment of the opening degree of the flow path by the valve element from the outside of the apparatus, and a control unit for adjusting the position of the operating member by driving the adjusting actuator based on the adjustment information.

A mechanical valve assembly for the control of a gas flow to a gas appliance. The mechanical valve assembly includes at least one input knob movably connected to a housing, a shaft assembly connected to at least one input knob, and a manually-operated valve located inside the housing and in between the inlet port and the outlet port. The manually-operated valve is mechanically connected to the shaft assembly, and the manually-operated valve is configured for opening and closing a gas flow between the inlet port and the outlet port.

A mechanical valve assembly for the control of a gas flow to a gas appliance, the mechanical valve assembly comprising: a housing; a gas inlet port associated with the housing; a gas outlet port associated with the housing; a timer-controlled valve operable to open and close a gas flow between the inlet port and outlet port; and a manually-operated emergency shut-off valve positioned between the inlet port and the outlet port, ahead of the timer-controlled valve relative to a direction of the gas flow through the mechanical valve assembly.

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. Exemplary components comprise a programmable clock apparatus comprising a mechanical clock mechanism and a mechanical mainspring, the programmable clock apparatus capable of opening and closing a control valve system by using a first connecting apparatus; the first connecting apparatus which converts the rotational movement of an of an hour dial and a minute dial to a linear movement of a valve plug component to open and close the control valve system and control the flow of media through it; and a turbine apparatus comprising a turbine shaft that has a turbine impeller on one end that is capable of turning when water flows through the control valve system, wherein when the turbine impeller turns its rotational energy is transferred to the mechanical mainspring of the programmable clock apparatus.
