This is a direct acting pilot valve, actuated by a pressure responsive
diaphragm, which tends to reach equilibrium with the set spring force.
Fully balanced trim ensures high accuracy and stability.
When used in a pressure reducing circuit, the pilot modulates closed
as downstream pressure rises above set point.
