Abstract: A manual/automatic and cold/hot faucet with a ceramic valve includes a main body adopting a ceramic valve that is connected with an automatic water exit passage and a manual water exit passage. The ceramic valve has a fixing member and a sliding member, with the sliding member sliding against the fixing member to command water to flow into the automatic water exit passage or the manual water exit passage. So the faucet can give water automatically or manually. As the ceramic valve is excellently resistant to abrasion, the present faucet can thus be durable, not apt to get leaked.

Abstract: In a valve device for selectively opening and closing a flow passage formed to open on a valve seat by a valve body through a resin-made seat, a hollow portion is formed on either one of the valve body and the valve seat and receives the resin-made seat therein, the resin-made seat has a thickness so that the resin-made seat partly protrudes from the hollow portion, and when the valve body is operated to close the flow passage, the resin-made seat is compressed to bring an end surface of the valve body into contact with the valve seat.

Abstract: An apparatus for controlling an internal pressure of a hermetically sealed chamber at a prescribed pressure level serves to relax pressure changes in the hermetically sealed chamber. The chamber is connected to an inlet passage for supplying air from an external environment through an aseptic filter, an outlet passage for discharging a gas through an aseptic filter, and an inlet valve and an outlet valve for selectively opening and closing the inlet passage and the outlet passage, respectively. The apparatus also includes a controller for controlling the inlet valve and the outlet valve to keep the internal pressure of the chamber at a prescribed positive pressure level. An elastic membrane of silicone rubber which is expanded or retracted depending on a change in the internal pressure of the chamber to relax the pressure change is connected to the outlet passage between the aseptic filter and the outlet valve.

Abstract: A demand valve for gas mixing comprises two or more flow control valves that are connected to separate gas supplies. The demand valve includes a common actuation mechanism, such as a diaphragm arranged to displace levers, each of which, in turn, opens and closes proportionally in a substantially constant ratio a respective flow control valve. Inhalation flow drawn through an outlet causes displacement of the diaphragm and hence opening of the flow control valves. Gas from the separate supplies is therefore mixed in a main chamber to a substantially constant composition, regardless of the flow rate demanded, before being dispensed via the outlet.

Abstract: A controlling device for hydraulic consumers (10, 12) has one controlling valve (18) for controlling a supply pipeline (TReg) for the hydraulic consumer (10, 12) and a tank return pipeline (TRO). Because the control valve (18) is connected to an additional supply pipeline (TR) and constructed as a priority valve, the supply pipeline (TReg) receives priority preference of a fluid supply system over the priority of the tank return pipeline (TRO). A sensor circuit is realized which checks whether, in accordance with the load situation at the hydraulic consumer (10, 12), there is any need at all for a supply flow.

Abstract: A valve system enables use of a standard single line faucet with a water treatment system. The valve system may include a housing having ports for receiving untreated supply water, supplying water to a water treatment system, receiving treated water from the water treatment system and supplying treated water to a dispenser. The valve system includes an automatic shutoff device that prevents water from flowing into the water treatment system when the dispensing faucet is closed and allows water to flow into the water treatment system when the faucet is open. The valve system may include a pressure relief mechanism that removes pressure from the water treatment system when the faucet is closed and a check valve for maintaining a desired amount of pressure within the valve system.

Abstract: A valve operable to control flow between two adjacent pipe sections and having a system for relieving pressure from an enclosed cavity within the valve. The valve includes a first pressure port, a second pressure port, and a seal. When the valve is closed, the first pressure port is in fluid communication with one pipe section and the second pressure port in fluid communication with the enclosed cavity. The seal isolates the second pressure port from the first pressure port when fluid pressure within the enclosed cavity is less than a pre-selected valve and is displaceable to enable fluid communication between the second pressure port and the first pressure port when fluid pressure in the enclosed cavity is equal to or greater than the pre-selected value.

Abstract: A pressure regulator is capable of automatically regulating the inlet water pressure to a compressed air foam system (CAFS), thereby allowing direct connection between a high-pressure water source, such as a hydrant, and the CAFS. The pressure regulator includes an inlet, a valve that regulates flow from the inlet, and an annular piston that circumscribes the inlet and which is linked to the valve. The relative area of the inlet and the piston determine the maximum pressure that may be attained at the CAFS water inlet, due to pressure on the piston forcing the valve closed.

Abstract: A flow actuated valve includes a valve body, a diverter member, an actuator member, and a check disk. The valve body defines a first upper aperture, a second upper aperture, and a lower aperture. A check disk member connects to the actuator member to control the flow of fluid depending upon the direction of the flow of the fluid through the valve. When the check disk member is closed, the diverter member engages the actuator member to allow a first fluid to flow through the first upper aperture or to allow a second fluid to flow through the second upper aperture. In operation, the fluid is selected by changing the directional flow of the fluid to close the check disk member which causes the actuator member to engage the diverter member to either allow the first fluid source or the second fluid source to flow therethrough.
