 I. Overview 

 YX741X diaphragm adjustable vacuum regulator valve is installed in high-rise building drainage system pipes, the inlet pressure to reduce the outlet pressure of a need for special valves. YX741X adjustable vacuum regulator valve diaphragm rely on its own energy to the set outlet pressure remained stable plant, the outlet pressure is not due to changes in inlet pressure and flow changes, and the inlet valve control system equipped with a self-cleaning filter , the use of fluid properties, so that a larger proportion of larger diameter of suspended particles will not enter the control system to ensure unhindered circulation, so YX741X adjustable vacuum regulator valve diaphragm safe and reliable operation.
