Product advantages

Double sealing of valve ball and rear valve seat with metal and graphite

The back of the main valve seat is designed with a hard metal seal and graphite double seal. Even if the back of the metal valve seat and the valve body deform at high temperatures, graphite still plays a sealing role, ensuring the reliability of valve use, and the auxiliary sealing design of the secondary valve seat.

Double layer packing design

The valve stem adopts a double-layer packing design： Two layers of packing can form complementary seals (such as inner flexible seal and outer wear-resistant protection), effectively blocking medium leakage and significantly enhancing the reliability and service life of valve stem sealing.

Diamond spraying on valve ball and valve seat

Diamond coating. The diamond coating has a thickness of 300 μ m and a hardness HRC ≥ 80, which is much higher than the hardness of the medium catalyst, effectively solving the problem of valve sealing surface wear.

Extremely low coefficient of friction

The friction coefficient is between 0.03 and 0.05, and it has excellent self-lubricating properties, which makes the valve opening and closing torque small, easy to operate, and reduces self wear caused by friction.

Excellent wear resistance

The wear resistance is 2-3 times that of ordinary hard alloys (such as tungsten carbide), greatly extending the service life of valves under harsh working conditions.
