Fluorine lined flange butterfly valve is usually suitable for working conditions with temperature ≤ 200 ℃, corrosiveness or cleanliness requirements. Fluorine lined flange butterfly valve is a kind of polymer material with thick lining technology used in flow passage parts, valve body, butterfly plate and valve stem.

1. The double flow direction can bear pressure to realize the installation mode without flow direction restriction. 2. 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.

Gate valve is a kind of valve for medium connection and shut- off but not suitable for regulating. Compared with other valves, gate valves have a wider range of combined applications for pressure, service fluid, design pressure and temperature. According to the screw position of the stem, the gate valve can be divided into rising stem gate valves and Non Rising Stem Gate Valve .

The Cryogenic Globe valve is composed of valve body, disc, stem, bonnet, handwheel and seal. The bonnet is of lengthened neck structure. It is characterized by double compression sealing structure composed of upper packing and lower packing. The medium flow path is low in and high out. The inlet channel of the valve body is below the sealing surface of the valve seat, and the outlet channel of the valve body is above the sealing surface of the valve seat.

Milestone Valve Co. Ltd. is a manufacturer specializing in the production of valves. It independently designs, develops, and produces various industrial valves such as butterfly valves, gate valves, ball valves, and check valves; among them, the independently developed High performance double offset butterfly valve is more resistant to high temperature and sealed It has better performance, better stability and longer service life. It is widely used in petroleum, chemical, smelting and other industries.

The insulation gate valve is used for some heat preservation media. The heat preservation design can prevent the solidification or crystallization of heat transfer oil, steam and other media at room temperature.
