1. Design according to the most severe working conditions.
2. Bonnetless integrated forging valve body, the whole valve body without any welding and bolt connection stress components.
3. The Y-type structure valve body has the characteristics of improving the flow capacity and reducing the resistance.
3. The integral Stellite grade 6 valve head and Stellite grade 12 valve seat have good red hardness and erosion resistance under high temperature.
4. Advanced non rotating stem design can protect packing, minimize friction and reduce operating torque.
5. Non rotating valve head design, this design can ensure that the valve core and valve seat do not grind in the process of closing and opening, which greatly reduces the damage to the sealing surface, thus prolonging the service life.
6. Combined packing seal.
7. Reinforced two piece bushing.
8. Short and narrow sealing chamber.
9. Fully sealed stem drive system.
