Fixed structure, the ball and valve seat are completely sealed in the form of metal and metal. In order to ensure the reliable sealing of the valve under various temperatures and pressures, according to the different working conditions and requirements of users, a variety of advanced hardening technologies of ball and valve seat can be adopted, including supersonic spraying, nickel base alloy spray welding, special surface hardening, cemented carbide spray welding and the use of high-strength and high hardness ceramic materials. Intrinsically fireproof and anti-static to prevent the valve rod from flying out.

This product is widely used in coal chemical industry, black water, grey water, polysilicon, petroleum, chemistry, electric power, metallurgy, cement, sugar making, mining and other industries.

1. Matching of high-quality materials - suitable for hardening materials of coal chemical valves

2. Self cleaning structure - valve seat scraper design

3. Disc spring protection design - prevent the medium from entering the elastic element cavity and causing failure

4. Two way sealing structure - the sealing grade is required to reach grade VI

5. Quick opening and closing design - selection of high-quality control accessories

6. Stable valve torque - high precision processing capacity and assembly process flow ensure the stability of each torque
