Butterfly valve is one of the most commonly used valves in the industry. Both butterfly valves and ball valves are valves with a 90-degree rotation. For start, shut-off and regulating. By turning the lever, the valve stem drives the butterfly disc to turn 90 degrees, thereby opening or closing.
The butterfly valve can be driven manually or combined with an actuator, driven by a pneumatic actuator or an electric actuator, which will make your flow control more precise.
Advantages of butterfly valve
● Simple operation
● Easy to install and maintain
● Need less installation space
● Wide range of sizes, suitable for larger size pipes
According to the design of the valve seat, one of them is called an elastic seat butterfly valve. In this article, we will briefly introduce to you what is an elastic valve seat and its application.
What is an relastic seat butterfly valve?
Resilient seat butterfly valve means that the valve seat of the valve is made of rubber, and the butterfly plate is in contact with rubber instead of metal. Therefore, the elastic seat butterfly valve has good sealing performance and is not easy to be worn. Generally, the valve seat will be made of two rubber materials, EPDM and PTFE. If the valve seat is damaged, it is relatively simple to replace the valve seat, so the elastic seat butterfly valve is easy to repair.
Types of butterfly valves
The elastic seat butterfly valve can also be divided into wafer type, flange type and lug type according to the connection mode. Different linking methods can be applied to different pipelines to meet your needs for pipeline linking.
Application of elastic seat butterfly valve
● HVAC (For cooling water or hot water)
● Wastewater treatment
● Chemical
● Power plant
● FGD industry
● Food and beverage
● Paper and pulp
Summarize
The butterfly valve is an excellent valve, which is well suitable for flow control in various industries. If you need more information, or need to find a Chinese butterfly valve manufacturer, we are very happy to help you, please contact us
