We keep in mind that for valves, quality is always the most important. To make sure that our customers receive good quality products, we have established strict quality assurance systems. Now all our factories have own quality control system in designing and manufacturing and they are API6D, ISO9001 and PED/CE certified. As castings/forgings are the key point for valves quality, all our subcontracted foundries/forging plants are also ISO9000 and PED/CE certified and pre-audited to be approved by our own inspectors.
Although most of the valves are manufactured by conventional lathes with skilled workers, the latest computer technology were widely applied, such as CNCs for machining and AutoCad for designing. We have labs to guarantee all material tests and each valve should be pressure tested to be satisfactory before delivery. We have and subcontract all NDT tests like RT, PT, MT and UT to meet customer's demands. Material test report and pressure test report as per EN 10204 3.1.b will be supplied with our valves.
Although our usual guarantee period is 18 months from delivery date, we can guarantee that our valve will work well in their life circle and we will be responsible for any valve we sold. Our aim is to produce "zero leakage" and "long reliable service life" valves to minimum the "Total Ownership Costs".
