They are normally operated remotely by air cylinders, electric or pneumatic actuators, although manual versions through the customary hand lever, handwheel and reduction gearboxes can be accommodated. SPECIFICATION Construction is generally from Mild or Stainless Steel with the body of the valve formed from rolled steel angles or channels dependent on the size. The Damper itself is formed from two plates which sandwich, if required, a felt seal or alternatively it can be a single blade sized for close fitment to the valve body. The type selected is dependent on the amount of air leakage that can be accepted. The split spindle mounting system minimizes turbulence within the air stream and these spindles are mounted on either two or four bolt flanged mounted sealed for life bearings. Seals can be fitted if required through a simple ‘O’ ring or, on high temperature applications, the conventional stuffing box is utilised. The type of actuator, to suit the clients requirements or specification, can be added to all sizes and, on pneumatic versions, limit switches and single solenoid spring return valves are included.
