Pressure Reducing Valve

Pressure reducing valves are installed in residential water system to reduce and stabilise inlet pressure from the water network which is generally too high and variable for domestic systems to work properly. When input pressure is 1.0MPa or above, the output pressure is 0.15MPa to 0.45MPa; when the input is less than 1Mpa, the output […]
