The fixed ball valves are usually driven by pneumatic, electric, hydraulic and other power sources due to the large opening and closing torque under high pressure conditions. Some small-diameter models can be equipped with manual gearboxes to reduce operating intensity.
The fixed ball structure can withstand higher medium pressures, with a nominal pressure of Class 1500 or even higher, suitable for scenarios such as long-distance oil and gas pipelines, high-pressure chemical processes, etc.
The bidirectional valve seat design supports bidirectional sealing, and the sealing effect is not affected by the flow direction of the medium. It can achieve zero leakage in the transportation of flammable and toxic media.
For large-diameter valves (DN300+), the fixed ball structure effectively disperses force, avoiding ball deformation and making opening/closing operations more effortless for high flow systems.
The stainless steel ball valve is widely used in oil and gas long-distance pipelines and field extraction; high temperature steam and slurry conveying pipelines in metallurgy and power industries.
