JLLN150.XXP, also known as the electronic proportional pressure reducing valve, is a specialized equipment used for controlling the pressure in the process pipeline automatically. It consists of two units, namely the main valve and speed regulating valve, which are connected with the actuator. The main valve is provided with an upstream pressure regulating device, a set pressure display device, a pressure regulating valve and a pressure-reducing path, while the speed regulating valve is provided with a pressure-transmitting device, a speed regulating knob, and a speed regulating pipe. It is usually used as an accessory in regulating pressure, so as to reduce or maintain the pressure of the process pipeline.

Working principle of JLLN150.XXP

The pressure-reducing valve converts the pressure from the high-pressure source into a proportionally regulated low pressure output. This is done by using the pressure-acting force on the diaphragm to act upon the pressure differential created by the adjustable valve seat. This will cause the movement of the diaphragm to control the opening and closing of the regulating valve, thereby controlling the velocity and flow rate of the output according to the speed control knob setting.

The pressure-reducing valve works according to the following principle. When the upstream and downstream pressures are different, the pressure-reducing valve can adjust the output pressure automatically and keep the output pressure at the set value. However, when the upstream and downstream pressures become the same, the valve will close.

Application field of JLLN150.XXP

JLLN150.XXP is widely used in many industrial processes, such as process engineering, chemical, oil and gas, power industry and other related fields. Its primary application involves the regulation of pressure in a pipeline. It can be used to reduce the pressure of the medium in the pipeline, reduce the flow rate of the medium, and adjust the output pressure to a set value. In addition, it can also be used to maintain constant pressure in the pipeline, so as to ensure the stability of pressure in downstream equipment.

In summary, JLLN150.XXP is a highly advanced electronic proportional pressure reducing valve. It has a wide range of applications, and its working principle is quite straightforward. It can be used to maintain and adjust the pressure in the pipeline, as well as maintaining a constant pressure in downstream equipment. This makes it a highly useful piece of equipment in many industrial processes.
