A water-control system has a faucet, a base unit having at least one normally-open solenoid-operated valve coupled to a water inlet fitting and a water outlet fitting, control circuitry, and a first antenna, and an elongated foot switch, having a normally-open contact element, a battery, and circuitry including a second antenna. A water-supply conduit is coupled to the water-inlet fitting of the solenoid-operated valve, and a water line is connected between the water-outlet fitting of the solenoid-operated valve and a fitting at the adjustable faucet, and wherein, with the faucet open and water flowing from the faucet, stepping on the foot switch closes the normally-open contact element, causing a signal to be sent wirelessly from the elongated foot switch to the solenoid control circuitry, causing the solenoid-operated valve to close, stopping water flow from the faucet, and releasing the foot switch allows water flow to resume.

A handwashing valve structure includes a mounting structure, a dispensing structure, and a control structure. The mounting structure is configured to attach to a liquid vessel. The dispensing structure is configured to dispense a liquid from the liquid vessel and is movable between a closed position and an open position. The control structure is configured to move the dispensing structure between the closed position and the open position. The control structure is configured to be moved by pressure from a portion of a user's body to move the dispensing structure from the closed position to the open position. The dispensing structure is configured to automatically move from the open position to the closed position in the absence of any pressure from the portion of the user's body onto the control structure.

A high pressure valve includes a lever and a variable force generator for facilitating control of opening and closing the valve at high pressures. The high pressure valve includes a housing having a chamber providing fluid communication between a first port and a second port, a pin movable within the chamber between an open position and a closed position. A first end of a lever is coupled to the pin and a second end of the lever is coupled to a variable force generator. The lever pivots about a pivot point. A controller coupled to the variable force generator is configured to adjust a force applied to the second end of the lever by the variable force generator to control the movement of the pin between the open position and the closed position.

A magnetically toggled valve apparatus is disclosed. In at least one embodiment, a valve body provides a valve cavity sized and configured for allowing a commodity to selectively flow therethrough, the valve cavity providing a commodity input configured for engagement with a commodity input source, and a commodity output in fluid communication with the commodity input. A toggle plunger is positioned within the valve cavity, with a first end of the toggle plunger providing a plunger magnet, and an opposing second end of the toggle plunger configured for selectively contacting a valve seat provided by a base of the valve cavity, the valve seat being proximal and in fluid communication with the commodity output. The toggle plunger is configured for moving between a closed position and an open position. An actuating magnet is positioned adjacent and external to the valve cavity. The actuating magnet is configured for selectively transitioning between an active state and an inactive state.

The present invention includes an apparatus and method for a hands-free foot pedal to attenuate and interrupt suction that attaches externally around suction tubing, in the context of any system where the flow of suction is through tubing.

A new type of turnover lift foot valve, including valve body, opening mechanism, valve core, guide mechanism and recovery mechanism; the valve body is set with two guide mechanisms, which are symmetrical and on both sides of valve core. The guide mechanism is provided with main guide rod at one end and with guide groove; there is side guide rod extending into the guide groove; the side guide rod is provided with bearing sleeve. The recovery mechanism includes spring and spring cage, the spring is set between valve core and spring cage; the spring cage is connected to the guide mechanism. Guide groove of the foot valve is in arc shape, so that valve core can deviate from the right above of valve opening and fluid cannot flow into valve body not only from the side of valve opening but also from the right above, which increases flow rate, improves working efficiency and solves the problems of traditional lift foot valve that flow rate is small and unloading is slow due to blockage by valve core.

An actuator system for a fluid playground including a first elongated tubular member defining a first axially extending enclosure and having a first inlet connectable to a fluid source, and a second elongated tubular member positioned within the first tubular member, the second tubular member defining a second axially extending enclosure, and having a second inlet in fluid communication with the first enclosure and an outlet traversing the first tubular member. The outlet is connectable to at least one fluid playground device. A plug element is shaped to removably and sealably close the second inlet of the second tubular member. A resilient member urges the plug element towards sealing engagement with the second tubular member. A pressure exerted on a movable actuating element connected to the plug element causes its displacement away from sealing engagement with the second inlet, thereby allowing fluid flow to the fluid playground device.
