Actuator & Valve Springs

Precision-engineered compression springs and spring cartridges for spring-return pneumatic actuators, diaphragm actuators and fail-safe valve assemblies - built to last in demanding industrial service.

01. Fail-Safe Performance

Springs Engineered for Critical Valve Service

Regal Controls supplies a complete range of springs for control valve actuators - from heavy-duty spring cartridges for scotch yoke actuators to precision compression springs for diaphragm and rack-and-pinion actuators. Every spring is selected for the right load curve, life cycles and corrosion resistance demanded by the application.

  • Spring-return cartridges for pneumatic quarter-turn actuators.
  • Compression springs for diaphragm and globe valve assemblies.
  • Shot-peened and powder-coated for long fatigue life.
  • Custom load ratings to match actuator torque and stroke.

02. Materials & Manufacturing

Built from Premium Spring Steel & Alloys

Our springs are manufactured from high-grade spring steel, stainless steel and special alloys to suit ambient, high-temperature and corrosive environments. Each batch is heat-treated, load-tested and surface-finished for consistent performance across millions of operating cycles.

  • Materials: Spring Steel (EN-45, EN-47), SS 302, SS 304, SS 316 and Inconel.
  • Heat-treated and shot-peened for high cycle life.
  • Powder-coated / phosphated finish for corrosion protection.
  • 100% load-tested before despatch.

Why Regal Springs

Designed for Reliability, Built for Longevity

Every spring we supply is matched to the actuator's torque curve, valve break-out load and plant operating envelope - so your fail-safe stays fail-safe.

High Cycle Life

Shot-peened, heat-treated springs rated for millions of stroke cycles in modulating and on-off service.

Wide Temp Range

Alloy options for service from sub-zero conditions up to 400 °C in steam and process applications.

Corrosion Resistant

Stainless steel and special-coated finishes for offshore, refinery and chemical plant environments.

Made to Drawing

Custom OD, ID, free length, wire diameter and load ratings produced to your specification or sample.
