Product Details

Features:

1. The gate valve is suitable for cutting off or connecting the pipeline medium in petroleum, chemical, thermal power stations and other working conditions with a nominal pressure of 1.6~42.0MPa (Class150~2500 and a working temperature of ≤600°C).

2. The fluid resistance of the product is small, the torque required for opening and closing is small, there is no flow direction limit, the sealing is reliable, and the performance is excellent.

3. Co-based cemented carbide is surfacing on the sealing surface, with good wear resistance, corrosion resistance, scratch resistance and long service life.

4. The valve stem has been quenched and tempered and nitrided on the surface, which has good corrosion resistance and scratch resistance.

5. The nominal pressure ≥ 15.0MPa (Class900), and the middle cavity adopts a self-tightening sealing structure, and the sealing performance is enhanced with the increase of pressure, which ensures the sealing performance.

6. The valve is equipped with an inverted sealing structure, which is reliable in sealing.

7. The material of the parts, the flange and the size of the butt welding end can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
