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