BREATHER VALVE

According to API 2000 code, BS7244 and EN 12874. The BV is designed, manufactured and tested by HITEK

Breather valves, also called the Pressure/Vacuum relief valves, are special types of relief valves which are specifically designed for tank protection. The range includes pressure only, vacuum only, combined Pressure/Vacuum Valves and combined Pressure/vacuum valves with pipe-away, all available with flanged outlets or vented to atmosphere. Pressure/Vacuum Relief Valves are used extensively on bulk storage tanks 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.
