Multi-louver damper valve solution for industrial air and gas applications.

Multi louver damper valve

DESCRIPTION

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

Louver dampers are made as a welded assembly construction and usually made for modulating gas applications. They are composed of one or many parallel blades that work together as a mechanical system when actuator operates the damper. The installation of this equipment is done between conduit rectangular flanges, which flange drilling can be made according to customer specifications or PARAVALVESstandard. Blades may be oriented vertically or horizontally in the frame. Optimum number and width of blades can be determined after the full parameters of plant operating characteristics are known. Face to face determines the distance between flanges and this can also be taylor-made to comply with customer project. Wafer type or ButtWelding ends can also be supplied on request.

Our engineered louver dampers are made to work in both flow directions as a bidirectional design. Configuration blades may operate in parallel or opposed direction. Parallel blades offer tighter sealing and are primarily used for balancing or isolating duct flow. Opposed blade operation is used to maintain a straight gas flow through the ductwork and provides better modulating capability. The seat can be done as a swing-through blade 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 blades design can be made. For such cases, the seal is done in the space between blades while injecting air at a higher pressure than the one in the conduit. This system creates a pressurized chamber preventing gases from escaping.

D130 LOUVER DAMPER series are divided in different types depending on the number of blades. D131 model is reffered to one single blade design, D132 shall be selected for multiple blade design and D133 model for round multi-louver damper design. For both models squared or rectangular sections can be designed to comply with customer requirements. Different materials are available such as carbon steel or many stainless steel grades, which can ensure working temperatures up to 1000ºC.
