Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and a small rotational torque can be closed tightly.When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve sealing surface.Ball valve according to the connection can be divided into flange connection, threaded connection and clamp connection.Our ball valves also have fireproof structure and lock device.Wide range of applications, from small to several millimeters, large to several meters, high, medium and low pressure environments can be used.
We have Certificate of ISO9001 management system is obtained in 2000, TS manufacture license (The national special equipment for pipeline and valve) in 2006 and API 6D (American Petroleum Institute) license in 2012.The sales market cover North America and Southeast Asia.Our factory has a high quality control system and a dedicated quality control team, all the valves are inspected on API598 or API6D, thus we can offer good quality valves to customers.We have full lines of equipment from production, inspection to testing, like two lines of sand casting and two lines of investment casting, 208 sets of mechanical processing equipment.Our production capacity reaches 6800 Tons for different kinds of high, medium and low pressure valves, with over 50 models and 600 kinds of specifications.We have one-stop production capacity from research, design, development, forging, sand casting, investment casting, machining, assembly, testing, coating to packing.According to the standard of GB, JB, HB, ANSI and JIS, we manufacture ball valves, globe valves, gate valves, butterfly valves, check valves, drain traps, fluorine lined valves, pneumatic and electric steam control valves, relief valves and different kinds of flange, with various kinds of raw material (alloy steel, heat-resistance steel.stainless steel, carbon steel, ductile iron and gray iron), the working pressure is 1.6-4.8Mpa and temperature below 480°C.With staff team of good technology and high quality, positive corporate culture, we are dedicated to provide our customers with quality service, adhering to the concept of QUAIITY, EFFICIENCY, INNOVATION.
