The piston type adjustable pressure reducing valve is installed in the pipe of the high rise building to the drainage system. the pressure of the inlet pressure of a special valve. The valve is to rely on energy itself make the outlet pressure is maintained stable in the setting that is outlet pressure is not due to he change of inlet pressure and tow changes, and the inlet of the valve control system with a can larger proportion ot larger diameter of suspended particles will not enter the control system, to ensure smooth circulation system, so tne valve can ru and. system is, high strength, long service life. Piston type used for more than 450 caliber valve.
