An aseptic closure system for attaching to a container including an upper section and a lower section that are removably attached to one another. Each section includes a valve housing with a rotary valve mounted in a bore extending through the valve housing. The upper section has an inlet port and an outlet port, each with a conduit providing fluid communication through the port to an interior of the upper valve housing. The lower section is adapted to mount to a container. The lower valve housing includes two conduits that permit fluid communication through the lower valve housing to an interior of the lower section. The rotation of the rotary valves closes off flow through the conduits in the respective housings.

A switchable water-saving valve including a water inlet substrate formed as an annular body which has a housing and a water inlet portion. The water inlet portion is fixedly arranged within the housing and has a water inlet and a water outlet extending therethrough. A flow channel substrate is fixedly arranged within the housing below the water inlet portion. Guide holes are formed circumferentially at intervals on the flow channel substrate and extend therethrough and are in fluid communication with the water outlet. A switch holder is rotatably positioned below the flow channel substrate. First and second pluralities of water flow holes are arranged circumferentially in the top surface of the switch holder and penetrate the top surface. Water outlet holes are formed on the bottom surface of an aerator holder and are in fluid communication with the first water flow holes. When the switch holder rotates to a first position where the first water flow holes are aligned with the guide holes, water flowing into the guide holes flows out of the water outlet holes through the first water flow holes.

An output member (7) is inserted in a housing (5) so as to be movable in a left-right direction. A lock chamber (20) is provided to the right of the output member (7), as a first actuation chamber. Compressed air is supplied to and discharged from the lock chamber (20) through a first supply and discharge passage (24) provided in the housing (5). A first holding valve (30) provided to an intermediate portion of the first supply and discharge passage (24) is configured to close and open the first supply and discharge passage (24).

A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes at least one controller that wirelessly communicates messages with a portable user device. The system includes a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The controller is operable to cause the valve to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to the portable user device responsive to the determined water use condition.

Provided is a flow rate adjusting device including: an ultrasonic flow metering portion; a flow rate adjusting portion; a control portion configured to control the flow rate adjusting portion so that the flow rate of the fluid measured by the ultrasonic flow metering portion matches a set value; a pressure sensor configured to measure a pressure of the fluid flowing into an upstream side of a measurement flow channel from an inflow port; and a storage portion configured to store information that associates the flow rate of the fluid obtained from the propagation time difference measured by the ultrasonic flow metering portion, the set value of the target flow rate, and the pressure measured by the pressure sensor with each other when the control portion controls the flow rate adjusting portion.

Proposed are directional control hydraulic valves and a system including the same, the system including: a first valve controlling a flow of a fluid flowing thereinto from a first input port by being interlocked with a solenoid valve that is switched to an excited (on) state or non-excited (off) state; and a second valve connected to the first valve and controlling a flow of the fluid flowing thereinto from the first valve by a fluid flowing thereinto from a second input port or a third input port, wherein at least a part of the fluid having been passed through the first valve is discharged through a first output port and then flows into the second input port or the third input port. In addition, the system including at least two directional control valves may be provide, whereby multiplexing of the system may be implemented.
