In addition to the structural features of the slag lock valve to prevent misoperation, prevent the stem from flying out, set up the driving device installation platform, it also has the following technical features. Lock slag valve of the spheroid and the valve seat completely using metal to metal seal form, in order to ensure reliable sealing valve under various temperature and pressure, aimed at different operating conditions and requirements of users, you can use a variety of advanced ball and the seat of the hardening technology, including supersonic spray coating, nickel base alloy spray welding, special surface hardening, Hard alloy spray welding and the use of high strength and high hardness ceramic materials, the surface hardness of the ball and seat can reach HRC75, HRC90 or more. The inlet and outlet are wear-resistant tungsten carbide alloy. Sealing surface material not only heat resistance, friction resistance, impact resistance and other properties. Slag lock valve can be applied to most of the harsh working conditions. Especially in coal chemical industry, polysilicon, petroleum, building materials, metallurgy, electricity, mining and other industries are used more.

Four big advantage

1. Double blocking and laxative function;

2. Excellent sealing performance;

3. Anti-clogging technical solution;

4. Natural anti-static structure setting.
