Safety relief valve
Mobel：GPAx742
1. Use
In the water supply and drainage network system, the pressure wave can be quickly reacted and released quickly, and the pipeline and equipment can be damaged to prevent the pressure rising rapidly, and it can be used to protect the water supply pressure of the main valve.
Two. Characteristics
1 accurate and stable safety and stability pressure, once the overpressure, relief valve can fully open timely pressure relief;
2 the closing speed can be adjusted to eliminate the pressure fluctuation.
3 diaphragm drive mechanism minimized operation hysteresis.
4 can be installed in any position, without changing the pressure setting value or dismantling from the pipeline, it can be overhauled.
5 action is sensitive and reliable, and the friction resistance is small.
Three. Technical parameters
1 nominal pressure: 1 1.6 2.5 Mpa
2 adjustment range: 0.3-0.9MPa; 0.5-1.4MPa; 0.5-2.2MPa
3 open and closed action pressure: 0.05MPa
4 applicable temperature: 0-80 degrees centigrade
5 suitable medium: water and oil
