Adjustable Pressure Reducing Valve

D720/D920 Adjustable Pressure Reducing Valve

Product description :

DESN Hydraulic control valve is to provide high quality pipeline the function of action, a high performance valve without external force, widely used in high-rise buildings, water system, agricultural irrigation and so on, the hydraulic control valve to meet the requirements of different conditions of high performance.

Characteristic ：

• Adjustable downstream pressure.
• Completely free diaphragm.
• Sensitive and accurate pressure control.
• Simple and reliable design for easy installation and maintenance.

When the pressure backflow occurs, the downstream pressure will enter the upper cavity, so that the main valve tightly closed.

820 adjustable pressure reducing valve can reduce the upstream high pressure to the required stable pressure value, regardless of the flow change or the upstream pressure changes. Downstream pressure can be adjusted as required, the valve closes tightly when the downstream pressure exceeds the set value.
