In early September 2008, more than 20 pieces of unibody ball valves according to DIN standards for Taiwan customer were successfully manufactured. The valves successfully passed the on-spot inspection and accepted by customer with good comment. This means this new type of ball valve is developed by us. The valve is designed as fireproof, anti-static structure, blow-out proof stem design, and the design of ISO5211 mounting is convenient for customers to match easy automation. Compared with the ordinary ball valve, it with lower cost, without body leakage, it’s good to be used, instead of ordinary ball valves, in chemical petroleum and metallurgy industry which not require much for pipe cleaning.
