Key Features:

1. Pneumatic Actuation: The valve is equipped with a pneumatic actuator, which allows for automated and remote operation. The actuator can be configured for either on/off control or modulating control, providing flexibility in various 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. Hard Seal: The valve features hard seals, typically made from materials such as metal or ceramic, which provide excellent resistance to wear, corrosion, and high temperatures. Hard seals are ideal for applications involving abrasive or corrosive media.

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

5. Durable Construction: The valve body and key components are made from high-quality materials such as stainless steel, carbon steel, or alloy steel, ensuring long service life and reliability in harsh environments.

6. Fire-safe Design: Many pneumatic floating ball valves with hard seals 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.

Advantages:

• Automated Operation: The pneumatic actuator allows for automated and remote operation, improving efficiency and reducing the need for manual intervention.

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

• Durability: The hard seals and durable construction materials provide excellent resistance to wear, corrosion, and high temperatures, ensuring long service life.

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

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