Features
1, This product owns double eccentric structure, and has reliable sealing property.
2, It has long service time thanks to the sealing material of stainless steel and butyronitrile oil resistant rubber.
3. The rubber seal can be chosen to be on valve body or on valve disc according to different media.
4. Valve disc is made of frame structure, and has the characteristics of high hardness, large flow area and small flow resistance.
5. Overall painted. It can prevent effectively rust.
6. This product has double sealing function, and is unlimited by the flow direction and position when installation.
Comparative Advantages
1. Pneumatic butterfly valve needs small operation torque to move valve disc 0~90° , and the on/off service can be realized.
2. This product uses electric-pneumatic valve positioner. With electrical signal and compressed air as power, this product changes them as pneumatic pressure signal to alter valve body's rotation angle to control the media.
3. Pneumatic actuator has spring-piston cylinder and bend arm transfer structure, so the product owns large output torque and small volume.
Application
1. Power plants (ash handling, fly ash, lime and lime slurry, gypsum, filtrate etc. )
2. Coal industry(coal washing, lime slurry, coal seperation, etc. )
3. Steel plant(pulverized coal injection, steel mills and lime desulfurization MGO silicate, etc. )4. Paper industry(pulp control, paper MGO CaCO3, bleach, the filtrate NaOH, etc)5. Chemical plant(acids, alumina industry, mixture)
Markets: North America,South America,Eastern Europe,Southeast Asia,Africa,Oceania,Mid East,Eastern Asia,Western Europe
Connection Form: Flange
Application: Water Industrial Usage
