Gas & cylinder valves
Fire Protection Valve Production Line
Synchronous automatic assembly of the valve body, pressure gauge, stem and handle with vision-based pressure-gauge calibration.
Production challenge
Fire-protection valve assembly must coordinate the valve body, pressure gauge, stem and handle while setting the pressure-gauge pointer within a controlled angular tolerance.
Dading solution
Three synchronous machine modules complete component assembly and automatic transfer. Two vision systems use a combined algorithm to calculate and calibrate the gauge-pointer angle to the documented ±2-degree tolerance.

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.
Four-part assembly
Valve body, pressure gauge, stem and handle are assembled in one automatic production sequence.
Dual-camera calibration
Two vision systems calculate the pressure-gauge pointer position.
±2° pointer control
The documented calibration algorithm controls angular tolerance around the specified position.
Synchronous modules
Three connected machine sections assemble, inspect and transfer products automatically.
