ABSTRACT:
Rectangular poppet damper or valve has particular utility as an isolation damper in a fabric filter dust collector and includes integral gas flow turning means which are positioned so as to minimize pressure drop. The poppet plate is pivoted at one end to the floor of an inlet manifold and has a pair of gas straightening vanes attached to its underside. One of the vanes is near the pivoted end and the other is generally parallel to the poppet plate and has lead-in and exit portions which gently turn the gas about 90.degree.. Where the gases are to be directed to a plurality of collectors, a damper is preferably provided for each, with the angles of the various poppet plates being individually adjustable so as to divide the flow in any proportion desired.
