1. Select the appropriate installation connection according to the principle that the various hydraulic valves throughout the hydraulic system should be installed in a coordinated manner。
2. The appropriate transition valve diameter shall be selected in accordance with the flow required for control. If the diameter of the valve is greater than 10 mm, a liquid or electron-for-valve is chosen. It may not be used beyond the rated pressure and flow limits specified in the manufacturer's sample in order to avoid malfunctioning。
3. Select the appropriate slide valve function and the mode of pairing according to the working requirements of the hydraulic system。
4. Optimize appropriate switch valve manipulation controls based on automation requirements and host conditions. In the case of industrial equipment hydraulic systems, because the workplace is fixed and the power supply is stable, the choice is usually made to switch to the electromagnetic or electron valves; in the case of hydraulic equipment systems working in the field, the choice is made to switch to the valves manually because the host is often required to replace the work site and there is no electricity supply; and in the case of hydraulic equipment systems operating under harsh environmental conditions (e. G. Damp, high temperature, high pressure, corrosive gases, etc.), the option is to replace the valve with gas-controlled hydraulic pressure in order to ensure the safety of persons and equipment。

5. The pressure on the t-turner cannot exceed the specified allowable value。
For electromagnetic switching valves, suitable electromagnets are selected based on the power source used, service life, switch frequency, safety characteristics, etc。
7. Liquid and electron switching valves shall, according to the needs of the system, select appropriate lead control methods for the supply and discharge of oil, and determine whether the selected valves are equipped with, for example, a detoxifier or a process control mechanism, according to the working performance requirements of the host and hydraulic system。
8. Two electro-magnetic magnets of the two electromagnetic electromagnetic valves cannot function simultaneously, and the actions of the two magnets should be locked together in the design of the electro-control system of the hydraulic equipment。
When the electron-forward valves and the liquid-forward valves are supplied internally, measures should be taken to ensure the minimum control pressure at the midpoint of the three four-wire-for-the-life valves, e. G., m, h, k, etc., for which the main oil route is unloaded at the intermediate position, such as the back-pressure valves。
