Puhui brand PYX741X adjustable pressure reducing and stabilizing valve　

Adjustable pressure reducing and stabilizing valveIt is installed on the water supply and drainage system pipelines of high-rise buildings. A special valve that reduces pressure to a desired outlet pressure. The valve relies on its ability to maintain stable outlet pressure at the set value, that is, the outlet pressure does not change due to changes in pressure and flow, and a self-cleaning filter is installed at the valve control system. By utilizing fluid characteristics, suspended particles with high specific gravity and large diameter will not enter the control system, and the system circulation will be unobstructed, enabling the valve to operate smoothly. PYX741X adjustable pressure reducing and stabilizing valve system has sensitive action and long service life.

Working principle of adjustable pressure reducing and stabilizing valve

To understand the working principle of the adjustable pressure reducing and stabilizing valve, let's first take a look at its composition structure, which consists of a main valve, a needle type regulating valve, a pilot valve, a ball valve, and a connecting pipe system. The main valve body adopts a full channel, DC, streamlined design, and adopts two types of structures: diaphragm or piston. Set the outlet pressure by adjusting the spring pressure of the pressure regulating valve and the opening of the needle valve, and stabilize the outlet pressure through feedback from the connecting system and control room. The use of needle type regulating valves and pilot valves for self controlled water pressure does not require additional devices or energy sources. It is easy to maintain, less affected by pressure and flow rate, and has high accuracy in pressure control and pressure reduction and stabilization.

PYX741X Adjustable Pressure Reducing and Stabilizing Valve Size Data

The data of PYX741X adjustable pressure reducing and stabilizing valve shown in the table below is in millimeters. Due to the years we have been producing the PYX741X pressure reducing valve, our products have undergone new generations, and the size data has changed in several specifications. When reserving dimensions, we can refer to the new dimensions. If you need other special sizes, you can come to us to arrange customized production. The change in size data of the PYX741X pressure reducing valve model will improve the functional performance of the product while maintaining its original level, resulting in longer product quality and service life. Easy installation and construction.

PYX741X Adjustable Pressure Reducing and Stabilizing ValveTypical installation diagram

Installation of PYX741X Adjustable Pressure Reducing and Stabilizing ValveFrom the typical diagram, it can be seen that the pressure reducing and stabilizing valve installed in the pipeline system needs to be coordinated with other valves or used in conjunction with each other. In this installation case, the PYX741X adjustable pressure reducing and stabilizing valve is the main character, and its valve is installed in front of itY-shaped filter、Soft sealed gate valveA soft sealed gate valve is installed behind the valve. The purpose of installing a Y-shaped filter is to filter out impurities in the pipeline and ensure the normal and stable functioning of the pressure reducing and stabilizing valve. If pipeline debris enters the PYX741X adjustable pressure reducing valve chamber, it may cause the valve to fail to operate and affect pressure reduction. If the pipeline water is very clean, it can be left uninstalled. The pipeline setup in the picture is ideal, with a bypass pipeline.
