Flue gas valves

Flue gas valves

Flue gas ducts are characterised by large to very large bores and high to extremely high temperatures. The medium often concerns flue and exhaust gases that are discharged or fed at a low pressure. The shape and size of flue gas ducts are highly diverse, which means that the manufacture of flue gas valves often involves customisation.

Application

Depending on the exact location and function of a flue gas valve, very different requirements are set. In critical places, the valves must be 100% tight (zero-leakage), whereas a certain amount of leakage is almost always permitted in non-critical places. We offer different types of flue gas valves, depending on your situation.
