Cartridge valve design factors

    The importance of the design versatility of cartridge valves and their orifice lies in mass production. For the cartridge valve of a certain specification, for mass production, the size of the valve port is unified. In addition, different functions of the valve can use the same specification of the valve chamber, such as: check valve, cone valve, flow control valve, throttle valve, two-position solenoid valve and so on. If the same specification, different functions of the valve can not use different valve bodies, then the processing cost of the valve block is bound to increase, the advantage of the cartridge valve no longer exists. Cartridge valves are widely used in the field of fluid control functions, and the components that have been applied are electromagnetic directional valves, check valves, relief valves, pressure reducing valves, flow control valves and sequence valves. The extension of commonality in fluid power circuit design and mechanical practicability fully demonstrates the importance of cartridge valves to system designers and users. Due to the versatility of the assembly process, the versatility of the valve hole specifications, and the characteristics of interchangeability, the use of cartridge valves * can achieve perfect design and configuration, and also make cartridge valves widely used in various hydraulic machinery.

Cartridge valve small size, low cost

    The user benefits of mass production are evident even before the end of the assembly line. The complete control system with cartridge valve design can greatly reduce manufacturing hours for users; Each element of the control system can be tested independently before being assembled into an integrated valve block; Integrated blocks can be tested as a whole before being sent to users. Since the components that must be installed and the connected pipes are greatly reduced, the user can save a lot of manufacturing hours. Due to the reduction of system contaminants, the reduction of leakage points and the reduction of assembly errors, reliability is significantly improved. The application of cartridge valve is systematic and convenient. Taking wheel loader as an example, the cartridge valve assembly block is used to replace the power transmission control device which is difficult to diagnose and maintain due to continuous failure. The original control system has more than 60 connecting pipes and 19 independent elements. The volume is 12x4x5 cubic inches, which is 20% of the space occupied by the original system. The features of using cartridge valves are as follows: Reduce installation time, reduce leakage points, reduce easy pollution sources, reduce maintenance time (because cartridge valves can be replaced without removing the fitting)
