Sun Hydraulics RVCAKEN Cartridge Relief Valve

The Sun Hydraulics RVCAKEN Cartridge Relief Valve is an adjustable pilot-operated cartridge relief valve that screws into a Sun cavity to limit system pressure and guard hydraulic components from overpressure. Designed for installation in manifolds, hydraulic power units, and mobile or industrial machinery, it delivers precise pressure control and system protection across closed-loop and open-loop circuits. Key specifications include manufacturer Sun Hydraulics and model RVCAKEN, cartridge-style relief valve with an adjustable setting that depends on configuration; mounting in standard Sun cavity cartridges (NFPA/ISO cavity dependent); cartridge-rated flow that is system dependent; a hardened steel body with corrosion-resistant coating; seal materials available as Buna-N or Viton depending on configuration; and compatibility with mineral-based hydraulic oil (ISO VG fluids typical). It is commonly used in Sun manifold systems, hydraulic power units, construction equipment, industrial presses, and material handling machinery where maximum system pressure must be controlled and hydraulic overload prevented. Typical replacements in the field include RVCA/RVC series relief cartridges from Sun Hydraulics, as well as equivalents from Parker and Bosch Rexroth.
