Sun Hydraulics YPCI-LEN-CA-311 Cartridge Valve

Sun Hydraulics YPCI-LEN-CA-311 is a solenoid-operated pressure-reducing assembly that serves as a complete valve package when paired with the compatible three-digit Sun body. As part of Sun's screw-in cartridge valve system, this model combines a seven-digit cartridge code with a three-digit body code to define the exact hydraulic function; YPCI-LEN-CA-311 specifically designates a pressure-reducing role within a Y-assembly. The unit is used to limit system pressure delivered to downstream circuits or pilot lines, enabling stable operation of actuators and logic elements in hydraulic systems. In practice, this model appears in Sun's valve assembly catalog cross-reference schemes, which map this cartridge to a corresponding body and determine porting, mounting style, materials, and any optional modifiers. While the exact performance characteristics (such as set pressure range, port size, material finish, and mounting configuration) depend on the chosen body and solenoid variant, the YPCI family is designed for solenoid actuation and integration into a Sun cartridge-based ecosystem. Typical usage scenarios include hydraulic tooling, machine tools, and automated systems where controlled, electric-over-hydraulic pressure reduction is required. The YPCI-LEN-CA-311 can be ordered as a cartridge and body combination in line-mount configurations, consistent with Sun’s cross-reference practice for valve assemblies. For precise specifications, consult Sun Hydraulics’ catalog pages corresponding to the seven-digit cartridge and three-digit body codes used in the configuration.
