3 General Description & Operating Principle General Description Cartridge valves, also known as way valves or logic valves, conform to DIN and ISO standards. They have two operational ports and. The flow path between these two connections is controlled hydraulically by pilot pressure applied to. Depending on the control input, cartridge valves can be used as: Directional Control Valves (start, stop, directional control) Pressure Control Valves (pressure relief, pressure control, pressure sequence and unloading function) Check Valves (check valve function and pilot operated check valve function) 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 Oilgear product line contains valves of nominal bores,,,,,, and as per DIN, for flows up to, gpm. Moreover, Oilgear 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 and, where the main flow is hydraulically operated by a controlling pressure applied to the connection. 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 cover plate which encloses the cartridge valve and provides pilot connections from the port. Various types of pilot control can be mounted either to the cover plate or to an adjacent manifold face to provide direct control of the cartridge valve. The effective areas of the basic element are, and. Pilot fluid can be taken from port, or both and (with a shuttle valve) or an external source. Hydraulic fluid can flow through the -way cartridge valve from or. 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, to the pressures acting from the working connections and on the seating surface of and the annular area of. If the valve cone is open, by reducing the pressure seen at, the flow can move from and or vice-versa. y applying a control pressure at, the working connections 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, as a result of clearance tolerance between the cone and sleeve, the leakage can be eliminated by using a leakproof seat valve and hooking up the pilot connection 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, and from each other.
