Whessoe is a leading manufacturer of tank and flame protection products for the oil & gas, petrochemical and chemical industries.  Tank protection is provided through our full line of overpressure protection valves including breather valves, pilot operated relief valves, emergency vents, tank blanketing valves and floating suction units. Flame protection is needed wherever there is the potential to ignite flammable gasses and vapors that will propagate through a system. Whessoe’s complete line of flame arresters protect against these deflagrations and unstable detonations. The Whessoe line of products in combination with Anderson Greenwood tank products (low pressure pilot operated relief valves, blanketing regulators, specialty tank valves) and Varec tank products (vents, flame arresters, regulators) provide a full set of tank protection options to our customers.
