This is a direct-operated, spool-type sequence valve with a pilot drain at port 4. The pilot drain ensures that backpressure at port 2 does not influence the pressure setting. When pilot pressure at port 3 exceeds the predetermined pressure, the spool shifts and allows flow between port 1 and port 2. Pressures at port 1 and port 2 do not affect the spring pressure setting. Due to the dependent drain at port 4, the backpressure at port 4 will directly increase the pressure setting in a 1:1 ratio.
