                  [Essential information]

                         High pressure forged steel ball valves are mainly used for long distance pipeline transportation of petroleum and natural gas and urban gas pipeline system. Due to the long pipeline with the unique characteristics of the valve, which is considered in the design of its ability to withstand stress of pipelines, as well as safety, weather resistance, long-term use of the reliable seal, the structure design is unique stunt. The operation modes are manual worm gear drive, pneumatic, electric, pneumatic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, hydraulic, mechanical, hydraulic, hydraulic, mechanical, hydraulic, hydraulic, mechanical and hydraulic systems.
