Superposition valve, also known as superposition valve, is a device for fluid control. It is composed of a main valve and a number of auxiliary valves, mainly used to adjust the fluid pressure, flow and temperature parameters. The principle of the superposition valve is to adjust the working state of the main valve by changing the opening of the auxiliary valve, so as to realize the control of the fluid. The superposition valve has the characteristics of fast response, high precision and good stability, and is widely used in petroleum, chemical, metallurgy, energy and other industrial fields.

The structure of the superposition valve is complex, including the main valve, auxiliary valve, actuator and control system. The main valve is usually composed of a valve body, a valve core and a valve seat, and the on-off of the fluid is controlled by changing the position of the valve core. The auxiliary valve is used to adjust the opening of the main valve, such as regulating valve or plug valve. The actuator is responsible for transmitting the control signal and converting the control signal into mechanical motion to drive the movement of the spool. The control system is the brain of the whole superposition valve, which senses the fluid parameters through the sensor, and then adjusts the action of the actuator according to the set value.

In short, the superposition valve is an advanced fluid control device, its structure is complex, but it has the characteristics of fast response, high precision and good stability. By reasonably adjusting the opening of the main valve and the auxiliary valve, the superposition valve can accurately control the pressure, flow and temperature of the fluid and other parameters, and is widely used in various industrial fields.

A reversing valve is a device used to control the direction of liquid or gas flow.

A solenoid valve is a device that controls the flow of fluid. Its working principle is to control the opening and closing of the valve through the magnetic field generated by electromagnetic excitation. It consists of electromagnet and valve body two parts.
