Selection Criteria For Using Butterfly Valves

1. Suitable for making larger diameter valves (such as DN600 and above) 2. Butterfly valve should be used in occasions with short structural length requirements 3. It is not suitable for high temperature and high pressure piping system, generally used for mediums such as ≦80 degrees, ≦1.0Mpa crude oil, oil products, water and so on. 4. Since the pressure loss of the butterfly valve is relatively large compared with the gate valve and the ball valve, the butterfly valve is suitable for...

Why can triple eccentric hard seal butterfly valve be widely used

The triple eccentric hard-sealed butterfly valve is widely used in metallurgy, electric power, petrochemical, water supply and drainage, and municipal construction and other industrial pipelines with a medium temperature of 425 ℃ or less to adjust flow and cut off fluid. In the previous article, we introduced to you the sealing principles of various eccentric butterfly valves. As a component used to realize the on-off and flow control of the pipeline system, the butterfly valve has been obtained in many...

Factors to consider when replacing gate valves with butterfly valves

In recent years, the gate valve as a tool to control the amount of water and the direction of water flow, its form has also changed. In the past, the commonly used dual-use flashlight gate valve was gradually replaced by dual-use flashlight butterfly valves. The advantages of butterfly valves are small size, light weight, easy installation, and small resistance coefficient. Although the traditional gate valve is not easy to leak water, it is large; especially the gate valve with...

What is a Steel Flange?

A flange is a forged or cast ring of steel designed to connect mechanically sections of pipe or join pipe to a pressure vessel, pump, valve or any other piece of equipment. THE BASICS OF STEEL FLANGES Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding...

What is the Difference Between Resilient Seated, High Performance, and Triple Offset Butterfly Valves?

For many processes that involve fluid material moving through pipe systems, butterfly valves are needed to stop or regulate flow. With this mechanism, a circular disc is designed to move perpendicular to the passage from fully closed to fully open or anywhere in between. It’s somewhat like a dimming switch. From full light the user can turn the lights down or completely off at the desired speed and vice versa. Because of the many applications, designs are varied for the different types...
