Butterfly Valve

All you need to know about Butterfly Valve Factory

The disc of a butterfly valve acts as a gate that opens or closes the flow path. This design makes the valve bidirectional. For many industrial applications, the hydraulic system is responsible for the opening and closing of valves.
Because of their light weight and low cost, these valves are often used by industries that require fluid control. Additionally, many industries prefer this valve because of its small size and ease of operation and maintenance. Butterfly valves can be operated manually, pneumatically or electrically.
What is the purpose of butterfly valve?
Butterfly valves exist in almost all industries that require flow control. These might be as follows:
Irrigation
Oil industry
Compressed Air Service
Agricultural industry
Cooling and circulating water
Wastewater industry
Corrosive applications
Fireproof
Mud

How does a butterfly valve work?

Butterfly valves are mainly used as control valves. When the valve needs to be opened, a thin disc in the middle moves sideways; it is perpendicular to the hole, and the stem moves in the same way as the disc.
The size of this disc is almost the same as the inner diameter of the piper. When the valve closes, the disc and stem move sideways again. Throttling occurs when the flow control portion of the valve opens.
Matters needing attention when buying a butterfly valve
Sometimes the valve is not operating at optimal speed even though it is relatively new. Why is this happening? The answer lies in the knowledge and application of these valves. Understanding these considerations is part of extending the life of such valves.
Flow medium
Perhaps this is the most important consideration. Knowing the media type can narrow down the appropriate valve to use. Also, knowing the amount of corrosive or trapped slurry in the valve cavity is part of the consideration. Having said that, high viscosity media are not suitable for butterfly valves.
Plumbing Considerations
The valve should be able to withstand the weight of the piping system; otherwise, the valve may experience significant bending loads, resulting in leaks and internal damage to the valve.
Materials used
The material of the valve body, disc and seat should be able to withstand corrosion through the medium. Another fact to consider is the acid concentration, if the acid is indeed a flowing medium.
With this in mind, some acids become more corrosive when diluted. Knowing industry standards can help in deciding what valve to use.
