3 Way Diverter Damper Valves

Designed to divert high-temperature exhaust gases, these valves are generally installed on big bag filters or in waste heat recovery circuits, directing the gases to a heat exchanger, or alternatively, to the atmosphere through a chimney.

Diverter valves, also known as bypass valves, are essentially large three-way valves, with connections identical to those of the inlet and outlet ducts.

A sophisticated design and precise assembly, enabling the compensation of thermal deformations, along with high-temperature-resistant materials, are the most important features of our three-way valves. Efficient thermal insulation prevents heat loss and also protects the structure from the effects of high temperatures.

These diverter valves can also be equipped with an air sealing system to ensure optimal tightness.
