Product & Technology News
- This breather valve, also known as direct acting pressure/vacuum relief valves, are special types of relief valves which are specifically designed for tank protection.
- Pressure/vacuum relief valves are used extensively on bulk storage tanks, including fixed roof tanks with floating covers, to minimize evaporation loss.
- The valves prevent the build-up of excessive pressure or vacuum which can unbalance the system or damage the storage vessel.
- Pressure and vacuum protection levels are controlled with weighted pallets or springs and can be combined to provide the required pressure/vacuum settings.
- It is common to combine pallet and spring systems in one unit i.e. pressure settings require a spring section, whilst the vacuum settings use the pallet method.
