PRESSURE-REDUCING VALVE EN200X
A. PRESSURE-REDUCING VALVE Structure and purpose
EN200X Pressure-Reducing Valve utilizes the self-energy of the medium to adjust the pipeline pressure and control the outlet pressure of the main valve through adjusting the pressure reducing of pilot valve. The outlet pressure does not change along with the variation of the inlet one and the water quantity of the outlet. It features by reliable performance, easy installation, maintenance, debugging and check, long duration.
