Butterfly Valve Supply & Manufacture
What is butterfly valve?
The opening and closing part of the butterfly valve is a rotating circular butterfly plate. The butterfly plate rotates around the axis in the valve seat to achieve the purpose of opening and closing or regulating flow. The butterfly valve has a simple structure, small size and light weight. It consists of only a few parts and can be opened and closed quickly by rotating 90°. They are lightweight, have a small installation footprint, are less expensive, are quick to operate, and are available in large hole sizes.
Advantages of butterfly valves
Simple structure and operation:
The design is relatively simple, making installation and maintenance easy. The operation modes are diverse and can be operated manually, pneumatically or electrically. The torque is small and it is very suitable for automatic and remote control.
Excellent flow characteristics:
In the fully open state, its flow characteristics are close to that of a straight pipe, and the flow resistance is very small. It is suitable for high flow and low pressure difference situations.
Excellent sealing performance:
The sealing surface is composed of the contact surface between the soft sealing material and the valve plate. In the closed state, the pressure of the valve plate on the sealing surface is very large, thus preventing fluid leakage.
Wide range of applications
Can be used in a variety of media, such as water, gas, petroleum, chemicals, etc.
Long life and reliability
It has a long service life and its reliability and other performance indicators have reached a high level.
Different types of butterfly valves
Wafer butterfly valve
Wafer butterfly valve is characterized by compact design and light structure.It is suitable for low pressure and is usually installed between two flanges or wafer
Flange butterfly valve
The valve is equipped with flanges on both sides and can be easily installed between two pipes.Flange butterfly valve has good sealing performance and reliable operation.
Lug butterfly valve
It has simple structure, small size and light weight.The installation method is simple and can be quickly opened and closed through simple operations.

Grooved Butterfly Valve
For use in trenched piping systems for quick and easy installation.Grooved butterfly valves can be installed and removed quickly, making them suitable for applications requiring frequent maintenance or replacement.
Stainless Steel butterfly valve
Made of stainless steel for excellent corrosion resistance, durability and high temperature resistance.Offers a tight closure, reliable seal, low maintenance and long-lasting performance.
Eccentric butterfly valve
The eccentric butterfly valve uses an offset disc design to form a wedge-shaped gap between the valve disc and the valve seat.Better sealing performance can be achieved, especially under high pressure conditions.
