Precision Machinery

SHTF valve series, in match with pressure differential transmitter, are used for measurement of pressure difference of gas, flow rate of steam and liquid level inside passages. The valve is two-position and double-pass plug valve, good in sealing, simple and safety in operation. An ideal alternative for 3-valve group, it is suitable for oil, chemicals, metallurgy, electricity generation, light industry, food and stuffs, military and research institutions.

The mechanical machining center of BIA has a lot of precision machining equipment including wire cutting machines, electric spark cutting machine, digital controlled lath, digital control milling machine, jig boring machine as well as conventional lathes, boring machines, planning machines, grinding machines and milling machines. With experienced technicians and complete and strict quality control system, the center has been more than 30 years involved in the machining of aeronautical and astronautical vehicle wind tunnel test models and balances, produced hundreds of sets of precision models and aerodynamic balances, its excellent skills has devoted contributions to China’s aeronautical and astronautical mission. Since China’s reform and opening to the outside world, the center’s mechanical machining has stepped into market and the extensive national economy field. The center has established extensive cooperation with some steel and iron tycoons of former ministry of metallurgy and has done active contributions to the nationalization design of fast line material rolling mill and China’s steel and iron industry. The center has also machined large-size catamaran stings for a Hong Kong company. As top in quality, the center received warm praise.
