Gas & cylinder valves

American LPG Cylinder Valve Assembly Line

A fully automatic main-machine and dual-sub-machine architecture for four-direction valve assembly, thread sealant and laser marking.

Production challenge

An American-pattern LPG valve requires component assembly on multiple body faces, controlled reorientation and permanent product identification without manual transfer.

Dading solution

One main machine and two sub-machines complete four-direction assembly. The valve is turned automatically between operations, with online thread-sealant application and laser marking included.

Engineering priorities

The details that protect output and quality.

The final machine architecture is confirmed against customer samples, drawings, applicable standards and the agreed acceptance protocol.

Three-module architecture

A main machine and two sub-machines divide the multi-direction assembly sequence.

Four-face assembly

Components are assembled on four sides of the valve body with automatic turnover.

Online thread sealant

Sealant application is integrated before the relevant threaded components are completed.

Laser identification

Finished valves receive permanent marking without leaving the line.
