Butterfly Valve

The butterfly valve, also called the flap valve, is a valve with a simple structure. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and fast in operation, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties.

Butterfly valves are widely used. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, and liquid metal. It mainly plays the role of cutting off and throttling on the pipeline.

The variety and quantity of butterfly valves continue to expand, and are developing towards high temperature, high pressure, large diameter, and high sealing. Now butterfly valves have long service life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.

Large Butterfly Valve

Large Butterfly Valve

Large butterfly valve is a kind of butterfly valve, which can be divided into pressure maintaining type, locking type and energy storage type. The butterfly valve is suitable for the outlet of water pump and the inlet pipeline of water turbine. It is used as a closed-circuit valve and check valve to avoid and reduce the backflow of medium in the pipeline system and produce excessive water hammer, so as to protect the pipeline system. Today the hammer large butterfly valve will be introduced.

Eccentric Flanged Butterfly Valve

Eccentric Flanged Butterfly Valve

The flanged butterfly valve whose stem axis deviates from the center of the disc and the center of the body at the same time, and the sealing pair is oblique cone is called Eccentric Flanged Butterfly Valve. The Eccentric Flanged Butterfly Valve produced by Milestone Valve Company has a double eccentric flange butterfly valve and a triple eccentric flange butterfly valve. Compared with ordinary butterfly valves, the Eccentric Flanged Butterfly Valve has an eccentric structure design. The sealing surface is instantly separated when the valve is opened and closed, reducing friction. Extend the service life. It can be used in petroleum, chemical, water supply and drainage, metallurgy, pharmaceutical and other industries, and can be applied to a variety of corrosive and non-corrosive gases, liquids, and fluid-filled pipelines.

Lug Butterfly Valve

Lug Butterfly Valve

The butterfly plate of the lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0-90 degrees, which can play the role of flow regulation. When the butterfly plate rotates to 90 degrees, the valve reaches the maximum opening, easy to operate.
