Diaphragm adjustable pressure reducing valve is installed in the high-rise building water supply and drainage system pipes, special valve inlet pressure is reduced to a desired outlet pressure. The valve is to rely on its own energy that the outlet pressure remained stable in the set value, the outlet pressure is not due to changes of inlet pressure and flow changes, fitted with a self cleaning strainer inlet and valve control system, through the use of fluid properties, the proportion of larger, the larger diameter suspended particles will not enter the control system to ensure the system cycle; SMOOTH OPERATOR, safe and reliable operation of the valve. The system movement sensitive, long service life.

Note: the installation diagram of elastic valve seat seal or valve optional, suggest ≥ DN350 butterfly valve. The H value for reference purposes only, to the real actual size as。
