Hydraulic Solenoid Valve DHF08-228H Threaded Cartridge Solenoid Valve

Classification and application of cartridge valve:

(1) Cut-off valve: cut-off valve, also known as closed-circuit valve, its role is to connect or cut off the medium in the pipeline. Cut-off valves include gate valves, globe valves, plug valves, ball valves, butterfly valves and diaphragms.
(2) Check valve: Check valve, also known as check valve or check valve, its role is to prevent the backflow of the medium in the pipeline. The bottom valve of the water pump suction close also belongs to the class of check valve.
(3) Safety valve: The role of safety valve is to prevent the medium pressure in the pipeline or device from exceeding the specified value, so as to achieve the purpose of safety protection
(4) Regulating valve: Regulating valve includes regulating valve, throttle valve and pressure reducing valve, its role is to adjust the pressure of the medium, flow and other parameters
(5) diverter valve: The diverter valve category includes a variety of distributing valves and traps, etc., whose role is to distribute, separate or mix the medium in the pipeline.

Cartridge valves have many functions, are easy to form various systems, and are compact in structure. Especially for large flow and non-mineral oil media, the advantages are more prominent. Before the valve block is completed on the assembly line, the benefits of mass production to the user are obvious. The whole control system with cartridge valve design can greatly reduce the user's manufacturing time; The individual components of the control system can be tested individually before being assembled into one monolithic valve block; The integrated block can be tested as a whole before being sent to the user.

     Because the cartridge (seat valve) is pressurized closed, there is no clearance leakage of the slide valve.
Therefore, the application of cartridge valve is becoming more and more extensive, and the cartridge hydraulic system composed of cartridge valve is widely used in plastic, iron and steel smelting, casting and forging hydraulic machinery, engineering machinery, transportation and other large hydraulic equipment. Whether abroad or at home, the use of cartridge valve hydraulic equipment has been more and more, large hydraulic equipment using cartridge valve combination hydraulic system is one of the main trends in the development of hydraulic technology.
