How to distinguish between intake throttle valve and exhaust throttle valve?

Exhaust throttle valve is generally used in air pressure \x0d\ intake throttle valve is generally used in hydraulic pressure \ x0d \ x0d \ advantages of intake throttle valve \x0d\ 1) It has fast response speed and is easy to match the gas consumption of the system, thus keeping the pressure basically constant within a certain gas consumption range. \x0d\2) The design and installation are simple, and the simplicity of design also brings inherent reliability. \x0d\ Therefore, this adjustment is usually used in combination with other adjustments. The intake valve (cascade or capacity regulating valve) is used to adjust the intake air, which can automatically match the gas supply with the gas consumption, and it constantly changes the intake air according to the gas consumption. The function of EOJ is completed by pressure regulator, which directly depends on the system pressure. Compressor operation is used for preset pressure points in no-load and full-load range, and the operation is automatically controlled by the controller, with stable pressure and no major artery. In addition, in the case of maximum air volume, only less power is needed to maintain the pressure of the system, because it does not need a high upper limit pressure and other air intake control. The maximum horsepower of the control mode is 100% air volume, which is the nominal full load power under full load pressure.
