ERD620

ADVANCED VALVE TESTING FOR ENHANCED QUALITY CONTROL

The ERD620 is ATEQ’s latest innovation in valve testing, designed to ensure precise flow control, leak detection, and pressure monitoring. This compact and high-performance tester generates a pressure ramp to detect flow events, such as valve opening and closing, ensuring compliance with strict quality standards.

Equipped with a large color display, the ERD620 provides real-time monitoring of pressure levels and flow variations, helping manufacturers maintain consistent product quality. The instrument records critical parameters, compares them to predefined reject levels, and offers multiple communication interfaces, including USB, Modbus RTU, and Ethernet/IP, for seamless integration into production lines.

TECHNOLOGY

FLOW TESTER PRINCIPLE

Every flow generates a pressure difference between the inlet and outlet of the laminar flow element, and this variation is measured by the pressure transducer.

When the fluid (gas) enters the device 1, it moves through a calibrated flow tube 2 which causes a drop in pressure. The pressure drop is measured by a differential pressure sensor 3. The pressure of the part under test 5 is measured by the sensor 4.

Illustration demonstrating the laminar flow measurement principle

Sometimes a leak can be considered as a “small flow”, or a flow as a “big leak”. When your reject level is too high for other technologies, it may be necessary to use a laminar flow tester. A flow takes place between the pressure line and the leak hole of the part.

Our instrument features a laminar flow element across which our differential pressure transducer is connected.
