Integrated Valves
Integrated Valve is an all in one unit, in which the regulator and cylinder valve are combined into one.It can be used in one and two pipe installations with circulating pump. An integrated multifunctional valve device includes a surface member having a first port and a second port formed therein, a flexible disk member having a central portion and a surrounding portion, a first seat member extending outward from the surface member and coupled to the surrounding portion of the flexible disk member, a second seat member extending outward from the surface member and surrounded by the first seat member. The central portion is movable between an open port position to establish fluid communication between the respective ports and a close port position to stop the fluid communication between the respective ports. The second seat member is configured to selectively receive the central portion of the flexible disk member corresponding to the close port position. The integrated multifunctional valve device also includes an actuator member configured to selectively move the central portion of the flexible disk member into the open port position and the close port position. Valves are used to direct the flow of fluid in order to assist in the proper function of the systems in which the valves are used. Valves exist in many forms such as check valves, relief valves, multiport valves, ball valves, and the like. Usage of numerous valves to provide the necessary functions of a respective system can take up valuable space. Also, numerous valves add a layer of complexity to the design and/or cost of the system. In fluid containers, valves may be used to direct the fluid and/or air. Proper placement of numerous valves within the fluid container may require design tradeoffs thereto. Fluid containers such as removable ink cartridges to be installed in image forming apparatuses, for example, generally require a particular shape to conform to a fluid container receiver of the respective image forming apparatus. Thus, ink cartridges requiring particular housing shapes potentially further limit the available space for proper placement of valves. In examples of the present disclosure, an integrated multifunctional valve device is disclosed. For example, the integrated multifunctional valve device may include a regulator valve, a first pressure- actuated valve, a second pressure-actuated valve and a capillary relief valve. Multiple valve functions sharing one or more components thereof are integrated into one device. In examples, one or more of such valves may be check valves. Thus, the integrated multifunctional valve device can be placed in a single location and still perform a variety of necessary valve functions. Consequently, the integrated multifunctional valve device may result in efficient use of space and reduce valve placement constraints. Further, the arrangement of the respective elements of the integrated multifunctional valve device may enable the valve functions to perform in an efficient manner and provide durability thereto.
