With a plant area of 12000 square meters we have more than 350 employees with international management system. In 2000, 2005, in 2013 we passed the ISO9001, ISO14001, OHSAS18001 certification, and imported the TS16949 system. Committing to the pursuit of zero defect quality and low-cost manufacturing, we continue to meet customer needs and expectations. 1.Raw Material2.Rough Finish3.Finish Machining4.Assembly 5.Testing6.Marking7.Packing8.Storage9.Delivery We have been focused on the design and manufacture of precision metal parts since many years,accumulating long-term experience in the valve, used in air condition valve, industrial welding torch and high purity gases.As we know hydraulic valve is not only with high precision, but also needs sustained improvement and verification through many tests. Therefore, we have acquired many high precision machining tools and testing equipments. In order to ensure stable quality, all precision machining process are controlled by ourselves, Each employee takes work very seriously. All new products have to pass through tests of proof pressure, burst pressure, pressure drop,pressure holding, transient response characteristics, antipollution,environment(-40~80鈩?. Each type of valve passed over one million cycles life tests under 1.2 times of rated pressure. All products have to pass 100% strict inspection before delivery. The oil cleanliness of our test beds is periodically reviewed and always maintained at NAS6.Customized Hand Pump website:http://www.dahydraulics-valves.com/ |
