is perfect for assembly between the flanges on systems of gas conduit.
The standard damper model is designed for activity at pressures of upto
500 mbar, with temperatures of upto 800 ºC and advisable speeds below 30 m/s. It is a particularly air tight valve with a closing degree of 90% to 99%,
which can limit 100% if an air-sealing system is enclosed. The standard
model is designed to carry out the assembly in such a manner that the
drive shaft stay in a horizontal position. Although, there is an
assembly choice with the shaft in a vertical position on request.
disc is built flat, with reinforcing ribs, and are backed on two
semi-shafts. The flat disc system is perfectly rigid for the work
pressures of these valves, and it doesn't have
two-way dampers have utility of controlling the gases passage
circulating in the conduit. They are made up of a disc shutter or disc,
which turns on two semi-shafts. The butterfly dampers are usually
supplied as a single part, except for uses in which the unit dimensions
require special transport.
Seal Design: There
are two types of butterfly seal design. Depending on the application,
the choices are: swingthru (90 – 97% closure) for situations with dust
concentrations < 1000 mg/Nm3; and step seat (99% closure) suited for
applications requiring a high air tightness level.
Construction: Standard construction includes diameters ranging from 150 mm to 2000 mm; and on request, bigger sizes can be constructed.
is a supply of butterflies with bearings, set on the outside and
isolated from the packing. As a result, they are kept away from sources
of corrosion and heat thus increasing their utile life. Also, this
system allows for the changing of the packing without removal of the
bearings, which make future maintenance simpler.
