Stainless Steel Electric Knife Gate Valve with Multi-Turn Electric Actuator
- Application: Water treatment, paper-making, power industry, chemical industry, iron and steel industry, mining, food processing, petroleum, etc.
● There are two types of flameproof products: dⅠ and dⅡBT4
1) dⅠ is suitable for non-excavating working face of a coal mine;
2) dⅡBT4 is used for factories and suitable for the environment
● Outdoor type is used in places without flammable/explosive and non-corrosive media
● It is an explosive gas mixture of T1 ~ T4 group of Class ⅡA and ⅡB.
● Suitable Medium: Pulp, sewage, slurry coal, ash, slag-water mixture, gas.Technical Parameters of Valve Actuator
