Brief Information
Pressure reducing valve consists of the main valve and pilot valve, needle valve, ball valve, micro filter and pressure gauge of hydraulic control of system. After use, when the setting outlet pressure, stable outlet pressure automatically. This product use pilot valve to control themselves, do not need other devices and energy sources, convenient maintenance, pressure control accuracy is high, affected by the inlet pressure and flow rate is small, reduced pressure regulator is reliable.
This series valve products are widely used in high-rise buildings, living quarters and other water supply pipe network system and urban water supply engineering.
Working Principle
When the valve from the inlet water supply, water flows through a needle into the main valve control room, outlet pressure through the catheter to the pilot valve. When the outlet pressure is higher than the pilot valve spring set value, pilot valve to close. Control room to stop drainage, at this time the main valve to control the indoor pressure and close the main valve, outlet pressure is no longer increases.
When the valve outlet pressure down to guide valve spring set pressure, the pilot valve open, the control room to the downstream drainage. Because the pilot valve system of displacement is greater than the needle valve into the water, the main valve control room pressure drop. Open the main valve inlet pressure. Under steady state, the control room the same feed water and drainage, the main valve opening is changeless, outlet pressure stability.
