A、Light torque

l The partial balanced structure of patent design (patent No. ZL201320732225.7) is adopted to reduce the pressure acting on the spherical surface of the valve under high pressure, thus reducing the friction force.。

l Unique structure design makes ball and seat reliable lubrication。

l Balls and seats are made of high hardness and high performance ceramics, with good self-lubrication, low resistance to valve opening and closing, and smooth opening and closing.。

l Excellent wear and erosion resistance of ceramics ensures that the torque of the valve will not change significantly after long-term use.。

B、Wear resistance

Ceramics are sintered at high temperature above 1680 (> HRA85) and have very high hardness, so they can adapt to various high wear and erosion conditions.。

C、Corrosion resistance

Ceramic balls have excellent chemical stability. They do not react with most chemical media and can be stabilized under various esters, alcohols and hydrocarbons. Therefore, by choosing different valve body and stem materials, it can be used in a variety of corrosion-resistant occasions.。

D、No leakage

Precision grinding of ceramic ball and ceramic seat ensures no leakage. In many poisonous or corrosive situations, once leaked, it will cause serious damage to personnel and equipment.。
