Sun flush valve

Low side, 3-position, hot oil shuttle valve

Low-side (hot oil) shuttle cartridges allow hot oil to be diverted from the low-pressure side of a closed loop system. When both work ports (ports 2 and 4) are at equal pressures the valve is spring-centered to an all-ports-blocked position. When one of the work ports (port 2 or 4) sees a higher pressure the opposite work port is connected to the common port (port 3).

  • The spool incorporates a hydraulic stop that eliminates mechanical impact and therefore the potential for internal damage.
  • The hydraulic stop results in a small pilot flow from the high side work port (port 2 or 4) to the common port (port 3).
  • A unique feature due to the hydraulic stop is that the hot oil relief setting can be confirmed with the transmission in neutral.
  • NOTE: Low shift values can potentially result in charge pump pressure alone inadvertently shifting the valve. Use care when selecting shift pressure.
  • Although this valve goes into a 4-port cavity, the nose (port 1) is not used.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
