200X pressure reducing valve, is a use of the media to regulate their own energy and intelligent control line pressure valve. 200X relief valve for domestic water supply, fire water and other industrial water systems, by adjusting the pressure pilot valve, you can adjust the outlet pressure of the main valve. Outlet pressure is not due to changes in the inlet pressure, inlet flow varies, safe and reliable outlet pressure is maintained at the set value and adjust the setting as necessary to achieve the purpose of decompression. The decompression valve precise, stable, secure, reliable, easy installation adjustment, long service life. Anhui Zhen Huang Valve Technology Co.
