Description
Flow is allowed from 3 to 4 and blocked at 2 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 2 and 3 while blocking 4. The
spring chamber is drained to 4, thus any pressure at 4 is
additive to the spring bias and pilot pressure required for
shifting.
Directional spool type, direct acting,
external pilot internal drain
