Technical Feature
OPERATION:
This valve is an unbalanced, vent-to-open, 2-way logic switching element with an
integral pilot control cavity. It is spring biased closed and uses port ① as a pilot
source. With a pilot 2-way valve in the closed position installed in the T-8A cavity, the
logic element will remain in the closed position. With the pilot valve open, the logic
element will open providing there is a sufficient combination of pressures to overcome
the spring force. The force generated at port ③ , plus the spring force, must be greater
than the sum of the forces acting at port ① and port ② for the valve to remain closed.
NOTE: The pilot area (port ③ ) is 1.8 times the area at port ① and 2.25 times the area
at port ② . -
