1. the product structure adopts pressure seal bonnet design, reliable sealing and excellent performance.

2. the valve channel near the straight line of the flow path design, reduce flow resistance.

3. seal the two throttle surface design, reduce the scouring of the sealing surface.

4. the overall valve seat, rotating lifting valve stem, lifting position indication, more intuitive.

5. Socket butt welding or butt welding.

6. The valve stem surface is treated by super-dense wear resistance, wear and corrosion resistance, small open and close friction, to ensure that no leakage products.
