Block port 3 to open, spring biased closed, unbalanced poppet logic element
with pilot source from port 1
SERIES 3 / CAPACITY: 240 L/min. / CAVITY: T-17A
These unbalanced poppet, logic valves are 2-way switching elements that are spring-biased closed and have port 1
as a pilot source. With port 3 blocked, the valve will open provided there is sufficient pressure at port 1. With port 3
vented, the valve will close. The force generated at port 3 must be greater than the sum of the forces acting at port
1 and port 2 plus the spring force for the valve to open. NOTE: The pilot area (port 3) is 1.8 times the area at port 1
and 2.25 times the area at port 2.
