Product Details
Breather Valves, also known as direct acting Pressure/Vacuum Relief Valves, are
special types of Relief Valves which are specifically designed for
tank protection. The range includes pressure only, vacuum only and
combined Pressure/Vacuum Valves, all available with flanged outlets
or vented to atmosphere. 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.
