Backflow Preventer (BX)

Product Code: BX

Basic Applications:

The BX model is installed upstream of booster pumps, chemical plant pipelines, washing machines, etc

Product Description:

The BX unit combines unparalleled backflow prevention with an extraordinarily low head loss. The unit incorporates a double check valve system of two independently acting, spring-loaded, poppet-type check valves. These valves function along side an automatic pressure differential relief valve that has been designed to be “normally open” during abnormal flow conditions.

Features:

  • Effective Water Security Device Preventing Extraordinary Headloss
  • Length Reduced by 50%
  • Bronze Prevents Contamination of Potable Water
  • Simple & Easy Installation and Maintenance
These two features in combination with the unit’s reduced pressure principle have created a system that is the industry leader in safeguarding potable water supplies against the threat of cross-connection. The BX unit also consists of three test cocks to facilitate easy field testing and two easy-tight nuts that drastically reduce the time needed for installation.
