Description
Flow is allowed bi-directionally between 2 and 3, and
blocked at 4 until pressure at 1 rises to overcome the spring
bias against the spool. When this bias pressure is surpassed,
the spool shifts, allowing bi-directional flow between 3 and
4 while blocking 2. The spring chamber is sealed and vented
to atmosphere, allowing consistent shifting with only spring
bias pressure independent of conditions at 2 or 3.
Directional spool type, direct acting,
