200X減壓穩壓閥由主閥、導閥、針閥、球閥、微型過濾器和壓力表組成水力控制接管系統。200 X decompression by the main valve, valve on the valve and needle valve, ball valves, micro filter and up a hydraulic pressure gauge control over the system. Use, when adjustment for export pressure, can automatically keep stable outlet pressure. Red valve 200 X reduced pressure inside the valve using pilot valve to control, no other device and energy, easy maintenance, pressure control high accuracy, the inlet pressure and flow affect small, reduced pressure voltage stabilizer and reliable. Red valve brand 200 X reduced pressure inside the valve is widely used in high-rise buildings, living quarters, water supply network system and the urban water supply project.
