GB "BT" (bladdertank) foam proportioner

The GB “BT” is a high performance foam proportioner designed for use with bladder tanks and combines very high proportioning accuracy with a low pressure drop. The GB series comes in sizes from 2 inch up to 10 inch, and flow ranges between 110 to 24000 lpm (standard versions).
The flow range ratio of 1:10 (1:5 for ARC type foam) makes the GB a flexible component in a fixed foam system.
For maximum flexibility the GB proportioners can be modified to suit a unique system specification. It can be modified for adjustable proportioning ratio or for minimal pressure drop or flow rate higher than 100% without changing proportioner body size. The GB “BT” proportioners are standard equipped with check valve.
