The fully welded pipeline ball valve produced in our company is a split type cylindrical valve body structure, mainly jointed the valve body with the connector by automatic submerged arc welding. The ball body is supported by the two supporting plates on the upper and lower side and can be rotated 90° By valve stem and external device. The valve stem adopts the combination sealing structure, and be designed symmetrical bi-directional sealing valve seat based on double piston effect. It also has the advantages of automatic pressure drain, fireproofing and anti-static functions.
The valve material meets to the requirements of API6D, ASTM, ANSI, GB19672. The surface treatment of parts should be used different methods according to different working conditions. The resistance sulfide stress corrosion should be done according to NACEMR 0175.
