1300200178, also known as electro-hydraulic proportional flow control valve, is an electrically operated valve. It is a kind of directional valve commonly used in the circulation system of hydraulic system. It can control flow rate, pressure or liquid level. It consists of a pilot valve and main valve, and their working principles are different.

The application field of 1300200178 varies from single function to complex closed-loop control, such as aircraft, engineering machinery, machine tools, metallurgy equipment, offshore platform, injection molding machine, process control, test system, etc. The working of the 1300200178 can be divided into two parts: the pilot valve and the main valve. The pilot valve can be controlled electronically by solenoid valve and the integrated pressure transducer, which can convert the control current into a specific pressure. This pressure then passes to the main valve, so that the flow rate in the system can be adjusted.

The working principle of the pilot valve is to use the on-off control action of the solenoid valve to adjust the pressure of the pipeline, which in turn controls the opening and closing of the main valve, adjusting the flow rate. Through the total hydraulic pressure of the main valve, the flow rate of the system can be precisely adjusted. The pilot valve can be adjusted to adjust the flow resistance and flow rate with its internal throttling and pressure adjusting devices.

The main valve of the 1300200178 is composed of a main valve spool, a spool guide and a pressure guiding device. The spool is installed in the main valve body, connected to the pilot valve, and the pressure regulating device is composed of a cone orifice, a needle valve, and a flow control loop. The spool is connected to the actuator, and the flow of the system can be adjusted by the actuator moving up and down, thus changing the opening degree of the valve hole and controlling the flow of the system.

1300200178 is a multifunctional valve with variable flow rate, pressure control and liquid level control in the system. It is widely used in many areas, and its application field and working principles are closely related. It plays an important role in the circulation of hydraulic system, and its adjustable flow rate and pressure control allow it to enter a new field of usage.
