TBV & Oil Cooler Assembly

Thermal Bypass Valve & Oil Cooler

  • Full range of Stack Plate Oil Coolers from 5kW to 11kW
  • Proven reliability in high volume mass production
  • Plug-in TBV design with compact assembly package
  • Flexible plumbing connection interfaces available
  • Capable of withstanding harsh under-hood environments


Oil Coolers are used to cool the oil for both traditional engines and electronic motors. We share our internal in-house design selection tool with our customers to customize the coolers in the OEM early design phases. The TBV regulates oil flow and flow direction in order to self-control the operating temperature of the transmission. The integrated assembly eliminates several separate pipes and oil plumbing connections. The oil connections are pre-assembled on the assembly and leak checked before shipping from SANHUA Automotive.
