Hydraulic schematic of center section (1) Center section of lower main control valve (2) Check valve (3) Pilot pressure relief valve (4) Spring (5) Orifice (6) Pilot pressure reducing valve (7) Load sense valveHigh-pressure oil from the main pump flows through orifice (5). Pilot pressure reducing valve (6) receives oil from orifice (5) and supplies the pilot oil circuit through check valve (2). Once the pilot oil circuit has reached a pressure that will overcome the strength of spring (4), pilot pressure reducing valve (6) shifts. This action will create a passage for pilot oil to drain to tank. Check valve (2) ensures that the entire circuit does not lose pressure.Once the pressure drops below the force of spring (4), spring (4) will push the spool of pilot pressure reducing valve (6). Pilot pressure reducing valve (6) can now continue to supply oil through check valve (2).
