Butterfly damper valve solution for industrial air and gas applications.

Butterfly damper valve

DESCRIPTION

At PARAVALVES, every product is carefully engineered as all the neccesary parameters are studied to develop our solid and reliable butterfly damper valves.

Butterfly dampers are made as a welded assembly construction and usually made for on/off or modulating gas applications. The installation of this equipment is done between pipeline flanges, which flange drilling can be made according to customer specifications or PARAVALVES standard. Face to face determines the distance between flanges and this can also be taylor-made to comply with customer project. Generally these equipments are installed in a horizontal shaft-line position, but vertical assemblies are also possible with our damper valves. Wafer type or ButtWelding ends can also be supplied on request.

Our engineered BUTTERFLY DAMPER VALVES are made to work in both flow directions as a bidirectional design. The seat can be done as a swing-through disc without seat or the disc can directly make contact with a metal plate ensuring a maximum leak of 0.5%Kv value. Soft braided sealing option can also be supplied on request, providing a more tightness damper closing.

For applications where a full 100% tightening is requested, an air sealing system with double parallel disc design can be made. For such cases, the seal is done in the space between both discs while injecting air at a higher pressure than the one in the conduit. This system creates a pressurized chamber preventing gases from escaping.
