Brief introduction of butterfly valve
Butterfly valve uses disc that runs with stem as open-close part in order to realize open, close and adjustment of valve. Butterfly valve with lining use rather thick macromolecule material on flowing parts such as body, disc and stem, with perfect anti-corrosive capability, suitable for mediums of acid, alkali, salt and oxidant, reducer, organic solvent etc. in any concentration. It is ideal product for gas, liquid, viscid pipeline and container as stop and adjust equipment which use in systems of chemical, petroleum, pharmacy, foodstuff, steel metallurgy, paper making, water power etc. furthermore, it can replace gate, globe valve and other type of stop, regular valve.
Configurable characteristics
1.Small size, light weight, flexible operation and convenient installation and maintenance
2. Perfect reliably sealing performance, zero leakage, and long service life.
3. Characteristic of flow to straight line, most excellent regular performance.
4. Simple configuration, open and close quickly, open and close in 90 degree turning.
5. It can replace gate valve, globe valve, plug valve, rubber pipe valve and diaphragm valve etc.
6. Set pneumatic, electric actuator according to user's requirement, so as to meet the requirement of remote control and program control.
7. It can replace lining material of part, suitable for various mediums.
