The PERMA/flo HD rotary valves fill a gap in the market between the typical industry  standards of heavy-duty and our PERMA/flo XT & XL Extreme Duty rotary valves.

 

The PERMA/flo HD rotary valves are offered in the two most common sizes, 8” & 12”. The HD rotary valves have many of the same standard features of our PERMA/flo XT & XL extreme Duty rotary valves, but the main difference is that it’s rotor and seal shoe are cast in a heavy iron alloy with a Brinell hardness of 180-260 BHN.
