Quality Assurance and Quality Control for Valves
Valve Quality Control & Inspection Services
As a global quality assurance company, Pro QC International promotes the interests of the valve industry through tailor-made quality assurance and quality control solutions such as third-party inspections, welding inspections and nondestructive testing (NDT).
From water distribution to nuclear power to pharma, and oil and gas, valves are critical devices for a myriad of industries. They help ensure safety by regulating and controlling process flows. Therefore, valve failures can lead to disruptions and incidents, and sometimes the fluids are quite hazardous or erosive, so the valve quality must be of utmost integrity and reliability. Moreover, valve suppliers and buyers need to adhere to the varying standards and regulations of different regions. This factor creates diversity in technical specifications due to the wide application of valves in various industries.
With over 40 years of experience, Pro QC International supports manufacturers and buyers of valves to assess high-quality standards. We qualify new suppliers, improve manufacturing performance, and inspect product quality. Our range of quality assurance and quality control solutions for valves includes factory audits, NDT, welding inspections, coating inspections, hydrostatic testing, dimensional inspection, factory acceptance testing (FAT), pre-shipment inspections (PSI), and many more.
