Structure and commissioning requirements of 200X pilot operated pressure reducing valve

The main pressure reducing valve product names of China Pressure Reducing Valve Network include:Direct Effect-Type diaphragm Spring Reducing Valve,diaphragm Adjustable Reducing And Stabilized Valve,DJY Series Motor-driven Reducing Valve,Electric Double Seat Steam Reducing Valve,diaphragm-Type Reducing Valve,Features And Functions Of Corrugated Pipe Reducing Valve,GAS Reducing Valve,Hige Sensitivity Steam Reducing Valve,Internal Thread High Sensitivity Steam Reducing ValveThe following picture is the structure and schematic diagram of the 200X pilot operated pressure reducing valve. From the picture, it can be seen that the main components that make up this pilot operated pressure reducing valve are:

1. Valve body, internal valve disc, spring. The interception port in the picture is in a fully closed state, and it is located at the valve disc at the bottom of the valve shaft. From the figure, it can be seen that this valve has three main parts. The upper valve chamber has a spring, which is located in the upper valve chamber, and the middle part is the valve's internal organ; Below the interception port is the lower valve chamber.

2. The main valve is equipped with external components, including a pilot pressure reducing head, two copper pipes, and one needle valve. Copper ball valves are equipped on copper pipes for finished products with larger diameters above DN200. And pressure gauges can also be requested to be configured.

Please refer to the installation requirements for adjustable pressure reducing valves and the following requirements for the installation of 200X pilot operated pressure reducing valves:

1. It is recommended to install exhaust valves in the pipeline system to ensure stable operation of the pressure reducing valve.

During installation, attention should be paid to the direction indicated by the arrow on the valve body. For the convenience of maintenance, a certain space should be left around the pressure reducing valve.

3. The import and export pressure should not be less than or equal to the decrease in pressure stabilization performance (resulting in an increase in outlet pressure error).
