Two-way check valve SV6-10-2NCSP threaded cartridge hydraulic valve

Advantages of hydraulic system cartridge valves
     

       Because the cartridge logic valve has been standardized at home and abroad, whether it is the international standard ISO, German DIN 24342 and our country (GB 2877 standard) have stipulated the world's common installation size, which can make the cartridge parts of different manufacturers can be interchangeable, and does not involve the internal structure of the valve, which also gives the design of the hydraulic valve has broad room for development.
     

      The cartridge logic valve is easy to integrate: multiple components can be concentrated in a block body to form a hydraulic logic control system, which can reduce the weight of the system composed of conventional pressure, direction and flow valves by 1/3 to 1/4, and the efficiency can be increased by 2% to 4%.

      Fast reaction speed: Because the cartridge valve is a seat valve structure, the spool starts to pass oil as soon as it leaves the seat. On the contrary, the slide valve structure must finish the covering amount before starting to connect the oil circuit, and the time to complete the pressure relief of the control chamber and open the cartridge valve is only about 10ms, and the reaction speed is fast.
       

Structure and performance characteristics of threaded cartridge valve

   As shown in the figure, a two-way threaded cartridge type direct-acting relief valve plug-in of a typical structure is screwed into the two-way valve hole as shown in Figure 2a. The inlet and outlet 2 and the system are connected through the holes in the cartridge valve block. A sealing ring is installed on the plug-in. The plug-in can also be inserted into a standard plate valve body with a threaded orifice or a body with a standard oil thread to form a discrete plate or threaded valve. This is especially necessary for the test of threaded cartridge valves.

     In addition to the above two holes, there are three and four holes, and the new two way cartridge valve field has only two holes. The former is more simple, flexible and compact in forming various types of pressure, flow and direction valves. As shown in Figure 4, the new one-thread plug-in requires four plug-ins, as shown in Figure 5. Obviously the latter is bigger and more expensive.
