Test and marking bench for valve bodies

Ref : Valve-Stamp

The Valve-Stamp is a hydraulic test bench designed for pressure testing and simultaneous marking of valve bodies.

Multi-station productivity: The machine controls up to three independent test modules to process multiple valve bodies simultaneously.
Measurement accuracy: The system detects leaks as small as 0.056 ml/min using a highly sensitive pressure sensor and precision length control.

Main functions

The Valve-Stamp test bench is a hydraulic test bench designed for pressure testing and traceability of industrial valve bodies. It allows multiple components to be processed simultaneously.

Operating mode

The operational cycle is fully automated and protected by a high-strength polycarbonate cover whose locking mechanism is synchronized with the pressure cycle.

Installation and sealing: The operator positions the components in specific modules. Hydraulic pistons ensure that the openings are sealed.
Pressurization and measurement: Filling and venting are automated using a pump. Leak detection is then controlled by a pressure generator, coupled with a highly sensitive digital sensor that detects even the slightest drop in pressure.
Marking and traceability: While the parts are under pressure, an impact marking unit engraves the serial number onto the conforming parts. In the event of a defect, the system applies a distinctive mark to the affected area to immediately identify the rejects.
Data management: The PC software interface allows you to configure parameter settings, monitor measurements in real time, and automatically generate inspection reports in PDF or Excel format.

Benefits of the Valve-Stamp

Optimization of inspection rates

The system allows for the simultaneous testing of up to 3 or 4 valve bodies using nearly independent test modules.

Ensuring Marking and Compliance

A stamping system engraves the serial number directly during the pressurization phase, ensuring that each part is identified. In the event of a defect, the testing bench applies a specific mark to immediately isolate non-conforming products.

Quick adaptation to changes in production runs

The use of interchangeable modules secured with self-sealing connectors allows for switching between different body types without the need for tools. The system can thus be easily upgraded to accommodate new nominal diameters or increase testing capacity.

Reliability of leak detection

The high-pressure generator’s control system ensures highly accurate results. This sensitivity guarantees precise leak detection, even under the most stringent requirements.
