Wafer Damper Valves
BFV01-LT / BFV01-MT / BFV01-HT
Fully CNC machined for optimum resistance for heavy duty applications ! These dampers are primarily wafer design but can, if necessary, be produced with flanges, spool piece or lugg .
The valve is intended to be used as an isolating (shutoff) or control (regulating) valve in which closing is realized by turning the disc attached to the shaft in a range of 0-90°.
The valve is designed for bi-directional flow of the fluid where the tightness of the obturator depends on the design. Achievable class I - II - III according to Ansi FCI 70/2.
The valves are equiped with adjustable stuffing box and graphite braids.
Above 300°C, the valves are equiped with external bearing. It is possible to install a lantern ring in the stuffing boxes that will enable flushing and overpressure - securing a perfect tightness to atmospher in chemical applications.
The face to face of these valves are kept to the shortest pattern but can be extended on request.
