Key Features:

1. Forged Construction: The valve body and key components are made from forged materials, such as carbon steel, stainless steel, or alloy steel. Forging provides enhanced mechanical properties, including high strength, toughness, and resistance to impact and fatigue, making the valve suitable for demanding applications.

2. Floating Ball Design: The ball is not fixed in place and is free to move slightly within the valve body. When the valve is closed, the pressure of the fluid pushes the ball against the downstream seat, creating a tight seal. This design ensures reliable sealing and is particularly effective for low-to-moderate pressure applications.

3. Bi-directional Sealing: The valve provides effective sealing in both directions, ensuring leak-proof operation regardless of the flow direction.

4. Compact and Lightweight Design: Compared to trunnion-mounted ball valves, floating ball valves are generally more compact and lightweight, making them easier to install and suitable for applications where space and weight are considerations.

5. Durable Sealing Materials: The seats and seals are made from high-performance materials such as PTFE, reinforced PTFE, or metal, depending on the application. These materials provide excellent sealing performance and long service life, even in corrosive or high-temperature environments.

6. Fire-safe Design: Many floating ball valves are designed to be fire-safe, meaning they can maintain their integrity and prevent leakage even in the event of a fire.

7. Blowout-proof Stem: The stem is designed to prevent blowout, ensuring safe and reliable operation under high-pressure conditions.

8. Versatile End Connections: The valve is available with various end connections, including flanged, threaded, and welded ends, to suit different piping systems and installation requirements.

Advantages:

• High Strength and Durability: The forged construction provides excellent strength and durability, making the valve suitable for high-pressure and high-temperature applications.

• Reliable Sealing: The floating ball design ensures tight sealing, preventing leakage and ensuring efficient operation.

• Compact and Lightweight: The compact and lightweight design makes the valve easy to install and suitable for applications where space and weight are considerations.

• Easy Operation: The floating ball design requires relatively low operating torque, making the valve easy to operate.

• Versatile Applications: The valve is suitable for a wide range of applications, including oil and gas, petrochemical, water treatment, and chemical processing.
