🔧

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.

⭐

Key Advantages

✔

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.

✔

Stable and reliable sealing performance: The bidirectional valve seat design supports bidirectional sealing. The sealing effect is not affected by the flow direction of the medium, achieving zero leakage for flammable, explosive, and toxic media.

✔

Large caliber advantages: For large-diameter valves (DN300+), the fixed ball structure disperses force on the ball, preventing deformation and ensuring effortless operation in high flow systems.

📦

Packing

Standard export wooden case packaging ensures safety during international transportation.

🏭

Application Scenarios

The stainless steel ball valve is widely used in oil and gas long-distance pipelines, oil and gas field extraction, high temperature steam, and slurry conveying pipelines in the metallurgical and power industries.

Frequently Asked Questions

Q1: What is the benefit of a mounted ball (fixed) structure? A: It effectively disperses the medium pressure, making it ideal for high-pressure and large-diameter applications where opening/closing torque needs to be managed.

Q2: Does this valve support bidirectional sealing? A: Yes, the bidirectional valve seat design ensures a zero-leakage seal regardless of the flow direction.

Q3: What standards are these valves manufactured to? A: These flange ball valves are manufactured in accordance with the BS5351 standard using investment casting workmanship.

Q4: Can these valves be automated? A: Absolutely. While handle operation is standard, they can be driven by pneumatic, electric, or hydraulic power sources for industrial automation.

Q5: What are the main materials used for the valve body? A: Common materials include WCB (Carbon Steel), CF8 (304 Stainless Steel), and CF8M (316 Stainless Steel).

Q6: What is the operating temperature range? A: The standard operating temperature range is between -20°C and 130°C.
