Suitable for Carter excavator accessories proportional solenoid valve 333-8242

Because the threaded cartridge valve starts later than the traditional plate and tube type, and is limited by volume and layout, it has some early characteristics

It is not as good as the traditional plate and tube type, which is specifically manifested in the hysteresis of the relief valve, the shunt accuracy of the shunt valve, and the movement of the flow valve

State response performance and so on. As already mentioned, the early development of threaded cartridge valves was driven by the needs of walking machinery

Because they are limited by space and weight, they must use threaded cartridge valves, and the performance is not so demanding. With threaded cartridge valve

Now some companies' products have reached similar or the same level as traditional valves and are also used for fixed equipment

The hydraulic pressure. For the above technical and economic reasons, today, the integrated installation form of hydraulic valves has roughly formed such a pattern.

1) Large flow system, flow rate is roughly 400 to 1000 liters/min or more, the main circuit mainly uses the cap plate cartridge valve.

The control loop is composed of a plate valve, a stack valve or a threaded cartridge valve.

2) Mass-produced components, roughly more than tens of thousands of pieces per year, often use special valves or special valve blocks, which should also be used

Use some threaded cartridge valves.

3) The system with a small batch output, dozens of pieces per year, the use of superimposed valves is more economical, flexible, and the design production cycle is short.

The stacking blocks are also widely used in threaded cartridge valves.

4) Batch production in the middle of the system, the common use of application-specific integrated blocks. Among them, the flow of small systems, often all use snails

Corrugated cartridge valve. Some use ISO interface plate reversing valve and threaded cartridge valve.

5) In walking hydraulic pressure, due to traditional reasons, the reversing valve is also quite common to use the chip structure. Even if the reversal has been taken

Use electronic or pneumatic control of these remote control means, but also retain the handle, as a means of human intervention in case of failure. Other control valves

Integrated block with threaded cartridge valve.

6) The application of pure tubular components that can only complete a single function has become less and less. Even if, for various reasons, it is necessary to make

For tubular connection, a valve block with tubular interface composed of a threaded cartridge valve is also often used.

7) The application of plate type flow valves and pressure valves is also becoming less and less, and is replaced by a threaded cartridge valve made into a stack type.
