Product Spotlight: Air-Piloted Valves
The 125 and 250 Series twoposition, air-piloted valves feature a pressure-operated spring and pressure return.
Available in two
and three-way configurations, the
valves have flow rates to 27.5 scfm
at 125 psig and the 250 Series valves
offer rates to 75 scfm. The 250 Series
also comes in a four-way, five-port
configuration with common supply
and exhaust ports, and is available with an internal compensating orifice
to maintain actuated position
after the momentary pilot signal,
and a “trapped” pilot reserve to compensate
for minor leaks.
Both valves feature a short stroke
for cycling times to 600 cpm, have a
double diaphragm poppet that requires
no lubrication, and no sliding
or metal seals or O-rings.
