4” – 72” Groundhog®

4” – 72” Groundhog®

AWWA Butterfly Valve

Underground distribution and transmission systems are most often designed with 4” through 20” mains. For isolation applications the Pratt GROUNDHOG® butterfly valve is designed to be buried and forgotten until needed. Components are selected for long-term reliability, so the valves will provide service life equaling or exceeding that of the pipeline.

GROUNDHOG® valves in 4” – 72” sizes meet all requirements of AWWA C504. A Pratt MDT buried service actuator is standard, and either flanged, mechanical joint, push-on joint, wafer or Victaulic® coupling styles are available.
