Valve bridge

To products

Technical specifications

DIN: 1.2346 (AISI H11)
Alloy: GX38CrMoV5-1
Weight: 50 – 250 grams
Finishing: Shotblasting and hardening


With a valvebridge the rocker arm can operate two intake or exhaust valves simultaneously.


  • Fuel savings due to lower product weight and inertia
  • Suitable for mass production without post processing
  • Casting in hardened steel with an extremely smooth surface
  • Lower costs from cutting out the need for hardening and mechanical post-processing

Advantage of the CIREX casting process

CIREX Engineering optimises the design for mass production without post-processing. Solid design, optimum functionality at the lowest possible production cost. An oil channel can also be cast at the same time in the chamber where the valve stem fits (pocket). Lower weight through ‘Near Net Shape’ design. This results in decreased inertia of the valve mechanism, saving fuel. Component cast in hardened steel without extra post-processing, providing considerable cost savings.
