3 General Description and Operating Principle General Description Cartridge valves, also known as 2/2 way valves or logic valves, conform to DIN and ISO 3 standards.they have two operational ports A and.the flow path between these two connections is controlled hydraulically by a pilot pressure applied to X. Depending on the control input, cartridge valves can be used as: Directional Control Valves (start, stop, directional control) Flow Control Valves The preferred mode of mounting is the manifold block, which can be equipped with several valves depending on the hydraulic circuit for the specific application. Each valve is connected to each other in the manifold block. The Moog Hydrolux product line contains valves of nominal bores 1, 2, 32, 40, 0, 3, 0 and 100 as per DIN 24342, for flows up to 12,000 lpm. Moreover, Moog Hydrolux offers cover plates and pilot valves for a wide variety of functions. In addition to this, our product offering also contains cartridge housings for a great number of applications for subplate, pipe and flange mounting. Operating Principle Cartridge valves have two working connections A and, where the main flow is hydraulically operated by a controlling pressure applied to the connection X.The basic cartridge valve includes a valve poppet and sleeve which is normally held in the closed position by a spring.the poppet valve has a seated cone, giving a leakage free (dependent upon pilot control) condition across the two ports.the closing spring is retained by the control cover which encloses the cartridge valve and provides pilot connections from the X port.various types of pilot control can be mounted either to the control cover or to an adjacent manifold face to provide direct control of the cartridge valve. The effective areas of the basic element are AA,A and AX. Pilot oil can be taken from port A, or both A and (with a shuttle valve) or an external source. Hydraulic fluid can flow through the 2 way cartridge valve from A or A. A pilot valve can be used to directly control the switching function of the cartridge valve, either between two extreme positions, open or closed, or in any number of intermediate positions.the exact position of the valve cone depends on the ratio of control surface AX, to the pressures acting from the working connections A and on the seating surface of AA and the annular area of A. If the valve cone is open, by reducing the pressure seen at X, then flow can move from A and or vice-versa. y applying a control pressure at X, the working connections A to are shut off as the valve cone is closed by the seat mounting. If there is a pressure difference between connection and pilot connection X, as a result of clearance tolerance between the cone and sleeve, then leakage can be eliminated by using a leakproof seat valve and hooking up the pilot connection X to the working connection. If the desired function does not permit such a switching operation, a cartridge valve with an additional sealing surface can be used to seal the connections A, and X from each other.
