GLR300G-8 Butterfly Valve

Globe Models GLR300G and GLR300W Ductile Iron
Butterfly Valves are indicating type valves designed and listed for use in fire protection systems. These valves are rated
for a maximum working pressure of 300 psi (20 bar) and
provide a visual indication as to whether the valve is open
or closed. They are provided with 2 sets of factory installed
Form-C internal supervisory switches monitoring the valves
in the normally open position. These supervisory switches
transfer their electrical contacts within the first two revolutions of the handwheel towards the closed position. The valves are available with grooved end connections (GLR300G) or as a wafer style (GLR300W).
