Characteristics
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.
Advantages
1 Strong Adaptability to High-Pressure Working Conditions
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., far exceeding the pressure range of floating ball valves.
2 Stable and Reliable Sealing Performance
The bidirectional valve seat design supports bidirectional sealing (the medium can flow in from either side of the inlet and outlet), and the sealing effect is not affected by the flow direction of the medium. It can achieve zero leakage in the transportation of flammable, explosive, and toxic media.
3 Large Caliber Has Obvious Advantages in Application
For large-diameter valves with a diameter of DN300 or above, the fixed ball structure can effectively disperse the force on the ball, avoid deformation of the ball due to excessive medium pressure, and make opening and closing operations more effortless, suitable for high flow pipeline systems.
Packing
Standard export wooden case packaging
Application Scenarios
The stainless steel ball valve is widely used in oil and gas long-distance pipelines and oil and gas field extraction conditions; high temperature steam and slurry conveying pipelines in the metallurgical and power industries.
Frequently Asked Questions
Q What is the difference between a fixed ball valve and a floating ball valve?
A fixed ball valve has the ball anchored in place by trunnion bearings, which absorbs line pressure and reduces torque on the seats. A floating ball valve allows the ball to move slightly under pressure to seal against the downstream seat. Fixed ball valves are better suited for high-pressure and large-diameter applications.
Q What standard does this flange ball valve comply with?
This flange ball valve is manufactured in accordance with BS5351, a British standard that specifies requirements for steel ball valves used in the petroleum, petrochemical, and allied industries.
Q What is the operating temperature range of this ball valve?
This ball valve is designed to operate within a temperature range of -20°C to 130°C, making it suitable for a wide range of industrial fluid control applications including oil, gas, and chemical media.
Q Does this ball valve support bidirectional sealing?
Yes. This fixed ball valve features a double-directional sealing design, meaning it can effectively seal regardless of the flow direction of the medium. This ensures zero leakage performance and makes it ideal for transporting flammable, explosive, or toxic media.
Q What industries is this stainless steel ball valve suitable for?
This valve is widely used in oil and gas long-distance pipelines, oil and gas field extraction, metallurgical and power industries for high-temperature steam and slurry conveying, as well as high-pressure chemical process systems.
Q How is this ball valve packaged for export?
The ball valve is packaged in standard export wooden cases, which provide robust protection against damage during international shipping and handling, ensuring the product arrives in perfect condition.
