Pressure Reducing Valve

• 

It adjusts and controls the outlet pressure of the main valve to enable the outlet pressure of the main valve not vary with inlet pressure, enable the outlet flow rate of the main valve not to vary with its outlet flow rate.

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

Pressure Reducing Valve Working Principle

When water flows through the 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 gate valvekeeps 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 china pressure reducing valvecan 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 ZECO Valve Group.

As a pilot operated pressure reducing valve manufacturer, we can offer kinds of pressure reducing valve for sale, and the cost of prv valveis reasonable, if you have needs to buy water pressure reducing valve, please contact us.

As a china valve factory, we will do our best to meet all the needs of customers.
