High temperature metal hard seal forged steel fixed ball valve

  • Profile:

    The difference between high temperature metal hard seal forged steel fixed ball valve and ordinary soft seal fixed ball valve is that the latter is soft seal seat, while the former's ball and valve seat are hardened by special process. There are many hardening methods, such as integral nitriding, flame spraying, surfacing welding and so on (not limited to this). The selection of hardening mode depends on the working condition medium High temperature metal hard seal forged steel fixed ball valve is widely used in petroleum, chemical, metallurgy, papermaking, electric power, mining and other industries, especially suitable for high temperature and medium containing various dust and solid particles.

Product introduction

The difference between high temperature metal hard seal forged steel fixed ball valve and ordinary soft seal fixed ball valve is that the latter is soft seal seat, while the former's ball and valve seat are hardened by special process. There are many hardening methods, such as integral nitriding, flame spraying, surfacing welding and so on (not limited to this). The selection of hardening mode depends on the working condition medium High temperature metal hard seal forged steel fixed ball valve is widely used in petroleum, chemical, metallurgy, papermaking, electric power, mining and other industries, especially suitable for high temperature and medium containing various dust and solid particles.

Product features

1. Heightening bracket design can effectively solve the problem of heat dissipation.  
2. The main parts are forged products with dense materials and guaranteed safety performance.  
3. The flexible movable metal valve seat structure with cylindrical spring or wave spring preload is adopted. The design of sealing preload is reasonable and the closing and opening is flexible, which can effectively ensure the reliability of sealing.  
4. The ball is made of super British speed spraying wear-resistant alloy powder, and the valve seat is overlaid with Stellite cemented carbide and sprayed with other super wear resistant alloy materials.  
5. The sealing surface is finely ground, and the sealing is reliable.  
6. Full diameter channel design, small flow resistance and large flow capacity.  
7. The valve rod anti fly out design is safe and reliable. The anti-static function can be designed according to the requirements.  
8. Automatic pressure relief valve seat design, once the valve body cavity abnormal pressure rise, the valve seat will automatically release to the low pressure end, more safe.  
9. Both the upper and lower valve stems are designed with bearing structure, and the torque is lighter in the process of opening and closing.  
10. A variety of drive mode options: manual, worm gear drive, pneumatic, electric, hydraulic, pneumatic linkage, etc.; can also be used with the automatic transportation control.
