200X pressure reducing valve is a kind of intelligent valve which can regulate and control the pipeline pressure by using the energy of the medium itself. 200X Zang pressure valve used for drinking water fire water supply and other industrial water supply system, guided by adjusting the vacuum valve, the valve outlet pressure can be adjusted by the king. The outlet pressure change of the valve inlet pressure, inlet flow and change, safe and reliable outlet pressure will be maintained at a fixed value, and can adjust settings to Zang pressure to achieve according to needs. The valve has the characteristics of accurate decompression, stable performance, safety and reliability, convenient installation and adjustment, and long service life.

When the valve from the inlet water, the flow through the needle into the main valve control room, outlet pressure through the catheter to guide valve. When the outlet pressure is higher than the value of the pilot valve, the pilot valve is closed. Control room to stop drainage, at this time the main valve control room pressure to rise and close the main valve, the outlet pressure is no longer elevated.
When the valve outlet pressure is reduced to the pilot valve spring, the pilot valve opens, the control room to the downstream drainage. Due to the amount of water drainage system is greater than the valve guide valve, the main valve control room pressure drop. Inlet pressure to open the main valve. In the steady state, the control room inlet and drainage are the same, the main valve opening is constant, and the outlet pressure is stable.
