Product introduction:
Adjust and control the main valve outlet pressure, which will not be changed along with the inlet pressure as well as the variation of the main valve outlet flow. Applicable for living water supply, fire-fighting system and industrial water supply system.
Characteristics:
The valve uses full passage streamline design, of a small fluid resistance and a heavy flow, can reduce either dynamic or static pressure.
Principle:
The medium enters the lower cavity of the body to push the disc upward and, at the same time, enters the upper cavity of the diaphragm via the external control pipe of the main valve, where the pressure is adjusted by the pilot valve.
