Actuator Disc Springs

subsea-valve-springsMubea disc springs can be used throughout various applications, including control and safety valve actuators for deepwater subsea and special valve applications. Our team can supply you with the most efficient and highest quality springs, while providing the best customer service.

Subsea Applications

  • Trees
  • Manifolds
  • Jumpers

Valve Applications

  • Surface Gate Valves
  • Control Valves
  • Safety Valves

Disc Spring Stacks vs. Coil Springs


  • actuator-springsHigh spring load with small spring deflection
  • Better space utilization than with other spring types
  • High fatigue life and low creep tendency with correct dimensioning
  • Disc springs allow nearly any kind of characteristic curve
  • Modular construction: Different combinations of disc springs show different characteristic curves including parallel stack and series stack

Advantages of Mubea Disc Springs

  • Engineering & designing assistance
  • Raw material from own cold rolling mill up to 6mm
  • Own tooling shop
  • Complete inhouse-production from raw material to finished disc spring
  • Shot peening as a standard process for increased fatigue life
  • Customer oriented service (e.g. stack pre-assembling)
  • Special material for specific applications
  • Various protective coating
  • Own test laboratory
  • Self-centering stacks do not need any additional guiding. They reduce friction and are applicable for disc spring dimensions greater than 200 mm OD
