Description:
These are 4-Way, 3-Position, rotary disc, direct-operated air valves. Two different types of control are offered. The forged bronze disc and the cast iron surface upon
which the disc works are ground and lapped to provide a leak-proof seal. Air pressure
from the inlet port is confined beneath the disc, making the seal tighter as the
pressure increases, yet friction between the lapped surfaces is so low that only 15
pounds of force is required to move the lever at 100 PSI line pressure. The need for
packing to seal around the stem is eliminated. Recommended for stationary air cylinders, arbor
presses, and as a throttling valve for positioning air cylinders.
General Specifications:
Operating Pressure:
0 to 150 PSI ; Operating Temperature:
+18° to +200°F
