Product features：

1. The valve stem anti-flying structure: a step is set at the lower part of the valve stem, and the valve stem is installed from the inside of the valve body to prevent the valve stem from flying out.

2. Anti-static function: An anti-static spring is set between the ball and the valve body or stem, which can lead out the static electricity generated during the switching action.

3. Advanced valve seat: The valve seat is designed based on many years of ball valve manufacturing experience, with low friction coefficient and small operating torque. A variety of valve seat materials, suitable for a wide range.

4. Fire-resistant structure: Advanced fire-resistant design. After a fire, each leakage part is designed to be flexible graphite packing or stainless steel clamped graphite, which meets the fire resistance requirements and meets the requirements of API6FA and API607.

5. When the handle is operated, a flat-head valve stem is used, and the connection with the handle will not be misaligned, thus ensuring that the switch state indicated by the handle is consistent with the valve. In order to prevent the valve switch from being wrongly operated, a locking hole is provided in the fully open and fully closed position of the switch to ensure that the valve is in the correct position.

6. The valve adopts the most advanced support plate structure at home and abroad, which improves the service life of the valve and reduces the operating torque of the valve. Greatly extend the service life of the valve.
