Pressure Relief Valve Without Contact
- Details
These Pressure Relief Devices are recommended to be used on small distribution transformers. It can also be used for various other applications and on various tanks and compartments where any pressure build-up needs to be relieved ranging from 20kPa to 70kPa.
1.Material: brass
2.Glaze color: yellow
3.Working pressure range(bar):0.3--0.6
4.Connection: 1/4" NPT
5.Standard：ANSI
Application：
The pressure release valve is suitable for oil-immersed power transformer, power capacitor and intercepting switch to protect the oil tank.
When the oil-immersed transformer fails in operation, because of the coil overheating, part of the transformer is electrified, and the pressure in the transformer tank increases rapidly. At this time, the pressure release valve moves quickly within 2ms to protect the tank from deformation or burst. When the pressure in the tank rises again and reaches the opening pressure, the pressure release valve operates again until the pressure in the tank drops to normal. At the same time, it can also effectively prevent the external air, dust, impurities, water vapor and other entry into the running transformer, so as to protect the transformer from damage.
Our Advantage：
* Lightning-withstand
* Anti-corrosion
