The model 700B valves are available in larger sizes of 1", 1 1/2"
and 2" NPT. These are diaphragm operated valves available as
standard 2-way normally closed. Optimum flow rates are 1 to 40
gpm for the 1" version, 10 to 100 gpm for the 1 1/2" valve and 30
to 160 gpm for the 2" size. The valves come with an internal
bleed manual override. Water pressure loss is dramatically
reduced due to the straight-through flow path design. The valves
are manufactured from glass reinforced nylon and pressure rated
at 10 to 150 psi.
