Description of Reducing Valve
Pressure reducing valves are diaphragm-type hydraulic control valves that are actuated by hydraulic pressure within the piping system. The function of this valve is to reduce the high pressure to a preset low pressure, and although the medium flow or pressure fluctuates in front of the valve, the pressure behind the valve always remains constant and remains within the set pressure range.
The orifice connects the lower chamber and the outlet, making the valve’s response soft and stable; the ball valve controls the water flow from the upper chamber, making the basic valve action stable; the ball valve can be adjusted according to different working conditions; in an emergency, the ball valve It can also be closed manually to cut off the basic valve.
Advantages of Reducing Valve
1、Driven by the pressure of the pipeline system, it automatically utilizes the energy of the pipeline system to achieve energy conservation and environmental protection.
2、Controlled by the pilot valve, it consumes less energy, achieves precise pressure reduction effect, and has the function of stabilizing pressure behind the valve.
3、Double-chamber design, with full-open and full-close functions, slow closing will not cause pressure fluctuations, and the supported diaphragm is well protected.
4、It has an inner hole that connects the bottom cavity and outlet of the basic valve to ensure stable reaction, maintain stable pressure behind the valve, and avoid any vibration and noise.
5、The channel has direct flow, small friction loss, no vortex and turbulence, and reduces cavitation damage.
6、Long wheelbase directional design facilitates stem movement, stability, and no gap resistance.
7、Automatic balancing, large gap design at the connection between the disc and the valve stem, the disc can swing freely in the vertical plane, which can balance the tolerances of processing and sealing surfaces, the connection has good sealing performance and no leakage, which can reduce both dynamic pressure and static pressure. The effect of pressure.

      Application

      Pressure reducing valves are widely used in the chemical industry, pharmaceutical industry, high-rise building industry, industrial water industry, petroleum industry, and metallurgical industry.
      Notes on installation and debugging:
      All pressure reducing valves have completed initial debugging before delivery. During use, further debugging is recommended based on different working conditions.
      Once the piping system is stable, loosen the adjusting
