Our commitment to quality

ONERO VALVE runs an excellent Quality Management System to ensure its consistent quality, coming through the whole process from casting supply to final inspection and testing. By upholding high quality standards, our skilled team makes sure that we are delivering most reliable valves in the global market.

 

 

 

With the various testing equipments, ONERO conducts comprehensive mechanical performance, non-destructive, and chemical analysis tests during the daily operation. The equipments such as spectrometer, Positive Material Identification(PMI) device, hardness tester, thickness tester ,universal testing machine, tensile impact testing machine, automatic hydraulic valve tester, etc.

 

Each valve is tested for strength and air-tightness before leaving the factory. For some valves intended for special applications, ONERO also performs low emission test, high and low temperature cycle test, life test, fire test, cryogenic test, etc. When all materials are received at the factory, chemical composition analysis and mechanical performance review are performed to prevent nonconforming materials from entering the production line. Valve pressure-containing parts are subject to non-destructive testing such as magnetic particle testing (MT), liquid penetration testing (PT), ultrasonic testing (UT) and radiographic testing (RT) as needed. With the serial number engraved on the valve ensures that each valve is traceable.
