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.
Electric actuated butterfly valve is generally used in environmental protection, food, light industry, oil and other industries,electric butterfly valve is also used in HVAC and refrigeration industry, but also can be used in the industrial field and water treatment, electric actuated butterfly valve is widely used because of its own advantages, but there are advantages and disadvantages.
Read MoreSend InquiryMilestone Valve Co. Ltd. is a professional manufacturing enterprise specializing in the design, development, production, sales and service of pump valves. At present, the products have covered more than 20 provinces and cities across the country, and are exported to Southeast Asia, the Middle East, and Europe and the United States. The valve products produced are widely used in water supply and drainage, electric power, petrochemical, metallurgical and other industries. The Wafer butterfly valve produced is one of the more common types of valves in industrial pipelines. It is installed in the diameter direction of the pipeline and the rotation angle is between 0°-90°. When it is rotated to 90°, the valve is fully open. Wafer butterfly valve is characterized by simple structure, small size, light weight, and consists of only a few parts.

Read MoreSend InquiryDouble eccentric butterfly valve based on the single eccentric butterfly valve, the most widely used double eccentric butterfly valve is further improved. The structural feature is that the axis of the valve stem deviates from the center of the butterfly plate and the body. The butterfly valve seat can be separated from the butterfly valve seat quickly, which can reduce the unnecessary abrasion of the butterfly valve seat.

In the cylindrical channel of the handle butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When it is rotated to 90°, the valve is fully opened.

The design of all metal seal, the seat and sealing ring adopt steli alloy surfacing technology to solve the problem of poor sealing performance of butterfly valve under severe working conditions such as high temperature, high pressure and low temperature. triple eccentric butterfly valve can withstand pressure up to 2500 pounds, and the temperature resistance is as low as -196 ℃ to 850 ℃, the seal reaches 0 leakage and the control ratio is up to 100:1. 3.The triple eccentric butterfly valve seat and valve body are designed separately, and the valve plate and sealing ring are designed separately. The products can be matched and interchanged. The whole valve will not be scrapped because of the seal wear problem. triple eccentric butterfly valve can be used normally only by replacing the valve seat and sealing ring, thus reducing the use cost.
