Precision quarter-turn engineering

Valve torque, forged into production-ready gearboxes.

TurnForge Engineering helps valve manufacturers and actuator teams translate operating requirements into robust quarter-turn gearbox designs, complete with calculations, drawings, and production intent.

TurnForge Engineering hero

Design through release

A continuous engineering path from torque input to manufacturable detail.

What to expect

Engineering you can inspect.

Traceable logic

Assumptions, load cases, safety factors, and design choices are documented—not hidden inside a black box.

Production focus

Concepts are developed with materials, tolerances, assembly, serviceability, and manufacturing constraints in view.

Direct access

Work directly with the engineer responsible for the calculations, CAD, and design decisions throughout the engagement.

Engineering services

One disciplined path from requirement to release.

Engage TurnForge for a focused calculation, a gearbox concept, or the complete design journey. Each stage creates useful, reviewable outputs.

01Inputs & loads

Torque requirement definition

Establish the design basis from valve torque data, operating conditions, actuator interface, duty, safety margins, and governing constraints.

  • Break-to-open and running torque review
  • Load cases and design margins
  • Travel stops and interface requirements
  • Design-basis calculation record
02

Architecture & sizing

Develop reduction architecture, gear geometry, shaft and bearing sizing, housing strategy, interfaces, and packaging envelopes.

03

Production-ready definition

Complete 3D CAD, detailed drawings, tolerances, materials, bill of materials, and design review support for a controlled handoff to production.

The goal is not merely a gearbox that fits—it is a design whose loads, interfaces, assembly, and manufacturing intent are coherent.

Engagement options

Scope before spend.

Gearbox programs vary by torque, complexity, standards, and required documentation. These practical entry points keep the first commitment proportionate to the problem.

Focused review

Engineering consultation

A working session to review requirements, identify technical risks, and define the right next step.

Quoted by scope

Defined deliverable

Concept & calculation package

Torque basis, preliminary architecture, sizing calculations, packaging direction, and design review.

Fixed proposal

Full development

Production design program

End-to-end engineering through CAD, drawings, BOM, design reviews, and production handoff.

Milestone proposal

Start with the design basis

Bring the valve. Leave with a clear engineering path.

Share your torque requirements, interfaces, operating conditions, and current design stage. TurnForge Engineering will help define an efficient, defensible scope.
