What Are The Advantages Of Our Lined Ball Valve Compared With Others On The Market?

Lined Ball Valve: Designed based on years of experience in floating ball valve (trunnion-mounted ball valve) manufacturing, this valve seat offers low friction and low operating torque. A variety of seat materials are available for a wide range of applications.

2. Reliable Open/Close Handle: The flat-headed valve stem ensures a secure connection to the handle, ensuring the handle indicates the same open/close position as the valve.

3. Locking Device: To prevent accidental valve opening and closing, locking holes are provided in the fully open and fully closed positions to ensure the valve is correctly positioned.

4. Stem Anti-Flyaway Structure: A step is provided at the bottom of the valve stem to allow the stem to be lowered from the valve body, preventing it from flying out. It also provides metal-to-metal contact with the valve body in the event of a fire, ensuring a tight seal.

5. Anti-Static Function: An anti-static spring is installed between the ball and the valve body or stem to dissipate static electricity generated during opening and closing. 6. Fire-Resistant Structure: Advanced fire-resistant design ensures metal-to-metal contact at all leaking points (ball and body, center flange, and stem and body) in the event of a fire, meeting fire-resistant requirements and complying with API 6FA and API 607. Flexible graphite packing and gaskets are available for use in locations with stringent fire-resistant requirements to ensure no leakage.
