Blow-Thru Rotary Air Lock Valves |
 |
 |
| |
| Blow-thru
rotary valves are used for introducing fine free-flowing
material into pneumatic conveying systems. The valves in
this series have been designed for applications with
certain non-abrasive materials, where the product
required an assist to remove it from the vane pockets.
Meets low headroom requirements. The valves itself
becomes a direct component of the pneumatic system. |
| |
| Valves for
line sizes from 1 to 6 inches available. Fabricated or
cast construction. Rotors are eight-vane,
partially-filled type. Fabricated construction. Rotors
with adjustable tips are available as an option.
Inspection ports can be supplied and are recommended
when adjustable tip rotors are used. |
| |
|
Rectangular blow-thru valves are used for systems
requiring greater capacity without increasing the
overall height. Standard models are available in double
widths other sizes can be supplied on special order. |
