Introduction Of Fluorine-lined Ball Valve

Lined Ball Valve Operational Reliability
The low-friction Teflon used in the interlocking components (valve seat and stem bearing) of the valve stem Lined Ball Valve reduces operating torque. Furthermore, the long-term lubrication of the sealing grease allows for smoother operation.

Valve Seat Structure
Valve seats are available in two configurations: single-seal and double-seal. Single-seal valves generally have a self-relieving function, while double-seal valves utilize an additional safety relief mechanism on the valve body.

Valve Stem Extension
Valve stem extensions are suitable for underground and low-temperature applications. The extension size is determined based on specific requirements. Operation modes include manual, pneumatic, electric, and gas-hydraulic.

Safety Against External Forces
The valve body wall thickness is designed in accordance with high-pressure vessel safety regulations. It meets API 6D requirements for resistance to bending and withstands external forces, ensuring sufficient strength.

Valve Stem Gland Seal
The gland seal utilizes four O-rings and a sealant grease injection device, as shown in the figure. Applications: The Lined Ball Valve series can be used with various media, including water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing media, and urea. It is widely used in the chemical, petroleum, natural gas, and metallurgical industries. The Lined Ball Valve series can be driven by worm gears, manual, pneumatic, or electric.
