Long Service Life Rubber Sealing Butterfly Valve Dn150 Butterfly Valve Dn200
High Quality Anti-condensation butterfly valve dn200 with spindle
Product Description
Rubber lined butterfly valve is a kind of valve with thick polymer lining on the body and disc. The lining makes
the body completely isolate from medium and provides excellent anti corrosive performance. It is designed as a device to shutoff or regulate the working medium flow and installed in pipelines or vessels with medium of acid, alkali, salt and oxidant, reducing agent, organic solvent in chemical, petroleum, pharmacy, food, iron and steel smelting, paper making, water power plant etc. It can be served as gate valve, globe valves as well as other shutting off or regulating valves.
Features and benefits
1, Convey slurry, minium liquid left in the pipe, low flow resistance,
rapid open-close, frequent operation.
2, Zero leakage in air test. Good sealing in bi-directional.
3, Easy dismantle and maintenance. Suitable for both vertical and horizontal installation.
4, Simple structure, small volume and light weight. Sensitive and adjustment in 0-90 degree.
5, Various materials suits to various working medium and working conditions.
6, Simple and compact structure, low operation torque, light weight and labor saving, rapid
open-close in 0-90 degree return.
7, Straight line flow characteristics. Optimum regulating performance.
8, The open & close test up to 10 thousands times and provides long service life.
9, A variety of operating mechanisms, such as electric, pneumatic and hydraulic suits to remote and
program control up on request.
10, It can be served as gate valve, globe valve, plug valve, rubber tube valve and diaphragm valve
etc.
