Pressure Reducing Valve
Festures of pressure reducing valves for fire protection service
Sensitive and accurate pressure control
Adjustable static pressure and dynamic pressure
Outlet pressure does not fluctuate with inlet pressure
Full port, small fluid resistance
Fire Pressure Reducing ValveWorking Principle
When water flows through the check valve, water flows into the main valve control chamber through the needle valve, and the outlet pressure is imposed on the pilot valve through the guide duct. When outlet pressure is higher than the set pressure of the pilot valve, the outlet pressure does not rise any more; when the outlet pressure of the valve reduces to the set pressure of the pilot valve, the pilot valve opens, water is discharged out of the control chamber. Because the water discharged from the pilot valve system is more than the water inflow, the pressure in main valve control chamber reduces. The inlet pressure forces the main valve open. In a stable state, the water inflow and discharged water of the control chamber are equal. The opening of the main valve keeps constant, with stable outlet pressure.
Pressure Reducing Valve Installation and Commissioning
For operation, adjustment and maintenance convenience, the pressure reducing valve is typically installed on a horizontal pipe along with a backup pressure reducing valve group. Every grade of spring of the pressure reducing valve ;can only apply in a certain range of outlet pressure, and outlet pressure can be set only by adjusting the spring of pilot valve. For specific use, please consult ZECOValve Group.
