Product Advantages

1. The mid-line butterfly valve consists of a valve body, a valve shaft, a valve clack and a sealing ring, with a simple and compact structure. Compared with other valves, the mid-line butterfly valve is small in size, light in weight, easy to install, and saves space‌. 

2. The operating lever of the mid-line butterfly valve can rotate 360 degrees, making the operation flexible and convenient. Moreover, the opening and closing speed of the mid-line butterfly valve is fast, and the fluid can be cut off or unobstructed quickly‌.

3. The valve body and valve clack of the mid-line butterfly valve are made of stainless steel or corrosion-resistant materials, which have strong corrosion resistance. Therefore, the mid-line butterfly valve is suitable for handling a variety of media, including corrosive media‌.

4. The mid-line butterfly valve is sealed with an elastic sealing ring, which has excellent sealing performance. The contact area between the valve clack and the valve seat is large, and the sealing is reliable. In addition, the sealing ring of the mid-line butterfly valve can be replaced to extend the service life‌.‌

5. The mid-line butterfly valve has a two-way sealing function. It is not controlled by the flow direction of the medium or affected by the spatial position during installation. It can be installed in any direction‌.

6. The driving methods of the mid-line butterfly valve include turbine transmission, electric, pneumatic, etc. are optional, and the operation is flexible and convenient‌.

7. The mid-line butterfly valve may include a mid-line soft seal butterfly valve‌,mid-line soft seal electric butterfly valve‌, mid-line soft seal pneumatic butterfly valve‌, stainless steel soft seal butterfly valve, carbon steel mid-line butterfly valve, manual wafer butterfly valve, mid-line pneumatic butterfly valve, and soft seal wafer butterfly valve.

• Mid-line butterfly valves are widely used in chemical industry, metallurgy, petroleum, electric power, water treatment and other industrial fields. They are used to regulate the flow and pressure of fluids and control fluid transportation and distribution in industrial production‌‌.

• The mid-line butterfly valve plays an important role in the sewage treatment system. It is used to regulate the flow of water inlet and outlet, control water quality and water level, and ensure the normal operation of the sewage treatment system‌‌.

• Mid-line butterfly valves are widely used in water supply and drainage systems in the construction field to control fluid flow inside and outside the building to achieve safe and efficient operation of water supply and drainage‌.

• The mid-line butterfly valve can be used to adjust the flow of cooling water and heating water in the HVAC system to achieve temperature control and energy saving‌.‌‌
