Quality First

​Quality Control

In Master Valve,  we firmly believe in "Quality First" because our team understands our valves could be used in most severe conditions and the stake is high for our end users and environment.  And we also believe the top-notch quality is maintained through stringent procedures not the human interactions. That's why we established  vigorous testing procedures from vendor selection, raw material receipt all the way through final assembly testing to identify non-conformance as early as possible. Catching a defect on our shop floor before finished goods' leaving our dock is essential for quality management. Quality is our core value and commitment to our demanding customers in today's demanding global marketplace.   

The scope of our quality management system covers all processes directly and indirectly related to the design, manufacture, assembly, and test of our valves. Our goal is to deliver the highest possible quality at a competitive price.
