Abstract: A valve device (1) which includes a fluid inlet (4) a fluid outlet (5), a main valve seat (32) defining an aperture through which fluid may selectively flow from said inlet (4) to said outlet (5), a valve assembly (31), movable relative to said main valve seat (32) between an open position of said valve in which fluid may flow from said inlet (4) to said outlet (5), and, a closed position of said valve in which fluid flow is prevented, a control chamber (12), at least a portion of the wall of which is formed by said valve assembly (31), such that the volume of said control chamber (12) is variable depending upon the position of said valve assembly (31), a fluid passageway (7), providing fluid communications between said fluid inlet (4) and said control chamber (12).

Abstract: A fluid valve which opens for a predetermined time before automatically closing. The valve (101) incorporates a control means including a control chamber (103), a first/inlet passageway (102) and a second/outlet passageway (120). A flow control element (104) is provided in one of the passageways (102) or (120). A biasing means (117) normally biases the valve to a first/closed position (FIG. 3). An activation means (113) is adapted to move the flow control element (104) to an activated position (FIG. 4) wherein flow of fluid is then permitted for a predetermined time.

Abstract: A valve component (1), formed at least partly of resilient material, including a body portion (2), of generally overall cylindrical shape, a radial recess (3), provided within an end surface of said body portion, and a peripheral flange (5), extending outwardly from said body portion adjacent to said radial recess. The peripheral flange (5) of the valve component (1) is adapted to be secured to a valve casing in a manner such that axial movement of the valve component (1) is permitted between an open position, wherein flow of fluid is permitted between an inlet and an outlet, and, a closed position, wherein the flow of fluid is prevented.

Abstract: A valve device (1) including a fluid inlet (4), a fluid outlet (5), a valve seat (6), a valve member (3) movable relative to a valve seat (6), a control chamber (12), the volume of the chamber being variable depending on the position of said valve member (3), a fluid passageway (7) formed in said valve member (3), providing fluid communication between said fluid inlet (4) and said control chamber (12), a flow control element (8) provided in said fluid passageway (7) such that only a small flow rate is permitted to flow in said fluid passageway, a relief port (9) providing fluid communication between said control chamber (12) and either said fluid outlet (5) or an external outlet, and, a control means to control the position of said valve member (3), either directly or indirectly, and to thereby control the operating of said valve device (1), the control means including a plunger (2) selectively actuated by a solenoid (10).

Abstract: A valve device to control fluid supplied to a tank. The valve device includes a fluid inlet, a fluid outlet to expel fluid to the tank, a valve seat, defining an opening through which fluid is adapted to flow from the inlet to the outlet, a valve member, movable relative to the valve seat between an open position and a closed position, and, a control mechanism to operate said valve device. The control mechanism includes a control chamber, a fluid passageway between the control chamber and the inlet, a flow control element within the fluid passageway, a relief valve, movable between an open position and a closed position to selectively expel fluid from the control chamber to a relief port, and, a relief valve activation mechanism, to control the operation of the relief valve according to an amount of fluid in the tank.

Abstract: The present invention relates to an interactive label selection system that permits the user to quickly and conveniently locate label products having characteristics that meet the users needs. The user inputs desired label characteristics, and the system searches a database for label products that have or that approximate those characteristics. The search results are then output by the system for the user's review or for further processing. One embodiment of the invention relates to an interactive, electronic method for finding label products that are suitable to meet a user's label needs based on minimum and maximum label width and height dimensions that the user inputs into an input device. Minimum and maximum label dimensions are input into an input device at a remote location. The minimum and maximum label dimensions are then transmitted across a computer network to a server.

Abstract: A valve device comprising a first fluid port, a second fluid port, a valve seat and a valve member having a control chamber is formed at least in part by the valve member. A first passageway communicates between the control chamber and a first port and a second passageway communicates between the control chamber and a second port. A control valve is associated with at least one of the passageways to permit fluid flow therethrough and to urge the valve member into one of a seated or lifted position. A spring-biased restrictor is disposed within at least one of the fluid passageways to clean and prevent clogging of the fluid passageway.
