How to choose the pilot valve of two-way cartridge valve?

First of all, you should know what the pilot valve of the two-way disassembly valve looks like, what its function is, and how the two-way disassembly valve works. Pilot valves commonly used as two-way disassembly valves generally include: electromagnetic directional valve (the most common), proportional directional valve, proportional pressure reducing valve, proportional overflow valve, etc.

The pilot valve of the two-way reversing valve is installed outside the cover plate of the two-way plug-in. Can control the opening and closing of the cartridge valve core, and can use different rigid springs and control rods to control the flow, pressure, direction and other purposes.

As you asked, path and flow are concepts. The larger the path, the greater the traffic. The faster the spool opens and closes. However, the faster the impact, the greater the impact, so the pilot valve of the two-way cartridge valve is generally 6-way. For some small plug-ins, such as 16 size, the pilot valve of size 6 is relatively large. At this time, a baffle can be installed on the plug-in cover plate, which is generally 1. 1~ 1.6. Make the pilot valve smaller again.

The pressure depends on the load and the pressure set by the oil pump in the system.
