Weatherproof Breather Valve Introduction
Pilot operated breathing valve is used in liquid storage tanks and other containers or systems to prevent damage to these containers or systems due to excessive internal pressure or vacuum.
Compared with the standard breather valve, the pilot breather valve has two main advantages:
- it is air tight to the set pressure;
- when it is less than 10% of the set pressure, it is fully open.
These characteristics make its working pressure very close to the maximum allowable working pressure of the storage tank. High working pressure reduces evaporation and exhaust volume, thus reducing product loss and the cost of treating emissions.
