Industrial valve glossary
Technical terminology, definitions and key concepts of the sector.
Quality Control and Digital Tracking
To take quality control one step further, at Comeval Valve Systems we have digitalised the life cycle of our equipment. Every valve leaves our facilities identified with a serial number and a unique QR code, engraved or clearly labelled on its nameplate.
With a simple scan using a smartphone or tablet in the field, operators and maintenance managers gain instant access to the official product documentation without depending on scattered paper files.
What information do you get when you scan the QR code?
Industrial valve glossary
Direct access to the EN 10204 3.1 material certificate and to the records of the functional and hydrostatic tests performed on that specific unit.
