Discription

Product Overview

 

Pneumatic Floating Ball Valve features a full-bore design where the valve path aligns perfectly with the pipeline diameter, ensuring minimal flow resistance and near-zero energy loss. Engineered for high-sealing integrity, it is ideal for controlling gases, liquids, and steam. Additionally, it is well-suited for sewage and media containing fibrous impurities.

Applications: Petroleum, Chemical, Metallurgy, Light Industry, Papermaking, Power Stations, and Refrigeration.

Product Features

 

  1. High-Efficiency Flow: The O-type floating ball valve is available in full-bore or reduced-bore designs, ensuring low flow resistance and optimal fluid dynamics.

  2. Professional Integration: Equipped with a high-platform structure and ISO 5211 mounting standard, allowing for professional and seamless installation of pneumatic actuators.

  3. Blowout-Proof Stem: Features an internally mounted stem with a shoulder and PTFE (or reinforced graphite) thrust washer. This prevents stem blowout under internal pressure and reduces operating torque for easier manual or automated control.

  4. Anti-Static & Fire-Safe Design: Includes built-in conductive springs between the stem, valve body, and ball to eliminate static electricity, preventing ignition of flammable media.

  5. Secondary Metal Sealing (Fire-Safe): Designed with a double-protection fire-safe structure. In the event of a fire that damages the soft seals, the valve creates a metal-to-metal hard seal to maintain system integrity and prevent leakage.
