ERD620 – NEW COMPACT VALVES TESTER
After 46 years, and 275,000 testers installed in more than 5,000 customers worldwide, ATEQ presents its revolutionnary valves tester ERD620.
New electronic module, new measurement module, new interface, new accessories… All has been made to improve your quality control.
The purpose of the instrument is to generate a pressure ramp and is waiting for an event as a flow appears (ex: valve opening). A ramp down can also detect when valve is closed. The instrument will display the event pressures and compare them to reject levels. As an option the flow event can be replaced by a dry contact event.
ERD620 : APPLICATIONS
Opening valves, closing valves with flow detection…
Leaking levels with flow detection…
Pressure contact elements…

ERD620 : TECHNOLOGY
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.
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.
