Description
Variable ends stops design allows optimize seal leakage and thus offer both economic or qualitative performance demanding client requirements. We offer assembly valves in assemblies where one drive is controlled by two valves by means of handles and to enhance tightness on the space between the damper and air blower. When using the dampers at temperatures higher than 300°C mounted between the shaft and the housing external bearings. The specialty of this valve is the use the eccentricity in the design of seat metal/metal to achieve 100% tightness of flaps that are particularly suitable for high temperatures
