Gear box butterfly valve metal seal expansion butterfly valve
The expansion butterfly valve have performance of automatically compensating the pipe's thermal expansion and contraction with working temperature below 425℃ and nominal pressure under 2.5MPa. The expansion butterfly valves are designed as a device to shut-off or regualte the working medium flow and installed pipelines with medium of water or gas inperoleum, chemical industry, power plant, papermaking undustry, food industry, pharmacy, urban construction, and other municipal projects.
Features and Benefits:
1. Features in unique structure, light weight, rapid open-close, convenient and excellent operation.
2. In addition to the function of shutting off and regualting medium flow as well as compensating for thermal expansion and contraction, it also provides convenience for valve's installation and maintenance.
3. Easy replaceable sealing element with reliable sealing performance.
4. Integrated function of butterfly valve and pipe expansion provides significant cost savings.
5. Different material selected according to the working condition.
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 device to shut-off 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 well as other shutting off or regulating valves.
Features and Benifits:
1. Vonvey 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 adjustment in 0-90°.
5. Various materials suits to various working medium and working conditions.
6. Straight line flow characteristics. Optimum regulation performance.
7. Simple and compact structure, low operation torque, light weight and labor saving, rapid open-close in 0-90° return.
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.
