Applications Of Butterfly Valve

Butterfly valves are one of the most common valves on the market now. Butterfly valve can be divided into manual butterfly valve, electric butterfly valve and pneumatic butterfly valve according to the driving method. Butterfly valves have a wide range of applications.

Because the butterfly valve plate movement with wiping, so most of the butterfly valve can be used with suspended solid particles of the media, according to the strength of the seal can also be used for powder and granular media.

Butterfly valve structure length and overall height is small, open and close fast, when fully open, with less fluid resistance, when open to about 15 degrees to 70 degrees, but also for sensitive flow control, butterfly valve structure principle is most suitable for the production of large-diameter valves.

Butterfly Valve is recommended under the following operating conditions:

1. Request throttling, regulating and controlling flow

2. Mud Medium and solid particle containing medium

3. The requirement valve structure length is short occasion

4. Require quick opening and closing speed occasion

5. Situations with small pressure differences

In double-position adjustment, necking channel, low noise, cavitation and gasification phenomenon, a small amount of leakage to the atmosphere, abrasive media, you can choose the butterfly valve. When using the butterfly valve under special working conditions, such as throttling regulation or strict sealing requirement, or severe wear and tear, low temperature and deep cold, etc.

The soft seal butterfly valve is suitable for ventilation and dust removal of the two-way open and close and regulation of the pipeline, metallurgy, light industry, power, petrochemical systems, such as gas pipelines and waterways.

Metal wire sealed double eccentric butterfly valve is suitable for heating, steam, water and gas, oil, acid and alkali pipelines, as a regulating and intercepting device.

Metal sealing tri-eccentric butterfly valve can be widely used in petroleum, chemical industry, metallurgy, electric power, food, medicine, water supply and drainage, gas transportation, etc.
