¦ TWO way on-off poppet valve with exceptional operating
characteristics.
¦ High flow capacity with reduced space requirements.
¦ One piece cartridge housing ensures internal concentricity.

OPERATION
With air pilot off, pressure acts on port 1 to firmly close the main poppet
on the seat. Pressure acting on port 2 allows free flow, port 2 to port 1.
With air pilot on, the main poppet lifts allowing flow from port 1 to port 2
and restricted flow from port 2 to port 1 (unless free reverse flow option
is used).
