Pressure Reducing Valve

Pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. It is a kind of valve used for allocating the direction of water supply in the water supply system of fire fighting water and domestic water in parallel. When a fire breaks out, a large amount of water is urgently needed for fire fighting, so immediately cut off the domestic water to ensure sufficient water for fire fighting. When the fire stop water pressure reduction, the valve will automatically open and be in a normal open state to restore the domestic water supply. The valve makes the system not need to set up a special fire separate water supply network, saving the construction cost and water consumption greatly.
