Product advantages

Valve ball and seat all metal hard seal

The valve ball and seat are made of all metal hard sealing form, which has excellent high temperature and high pressure resistance characteristics and can maintain good sealing effect in complex industrial environments. It can effectively adapt to the high temperature and high pressure harsh working conditions in the fields of petroleum, chemical and other industries.

Diamond spraying on valve ball and valve seat

The surface of the sphere and the sealing surface of the valve seat are hardened using diamond spraying technology. The coating and substrate belong to micro metallurgical bonding, effectively avoiding the peeling of the hardened layer during long-term operation. After hardening, the surface hardness reaches 80HRC, and the effective thickness of the hardened layer is 0.3mm, which can effectively resist the cutting and scratching of hard particles in the slurry.

The valve ball and valve seat are gradually mirror polished 360 degrees

The grinding of the sphere and valve seat adopts a unique 360 degree gradual mirror matching grinding technology, which can create a mirror like vacuum state between the sphere and valve seat, achieving zero leakage standards in terms of sealing performance and sealing performance after frequent switching.

Scraper type structural design

The opening and closing process has a self-cleaning function, effectively preventing the deposition and adhesion of media between the ball and the valve seat, ensuring smooth and continuous valve opening and closing without jamming, widening the sealing surface of the valve seat, and increasing the sealing performance between the ball and the seat.
