    Metal seated gate valve for abrasive media

    The Milestone Metal seated gate valve for abrasive media valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The Metal seated gate valve for abrasive media has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge.
  • Wafer Type Hard Seal Butterfly Valve

    Wafer Type Hard Seal Butterfly Valve

    The wave type hard seal butterfly valve produced by milestone Industrial Co. Ltd. adopts stainless steel sealing ring. The elastic sealing ring has three eccentric contact with the butterfly plate, which realizes the effect of separating the sealing surface at the moment of opening and sealing at the moment of closing, so as to prolong the service life and achieve the best sealing performance. Therefore, wave type hard seal butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas, water supply and drainage and other corrosive medium pipelines with medium temperature ≤ 550 ℃. Wafer Type Hard Seal Butterfly Valve is the best device to regulate flow and cut off fluid.
  • Stainless Steel Globe Valve

    Stainless Steel Globe Valve

    Stainless steel globe valve is a kind of valve, which belongs to forced sealing valve. When the valve is closed, pressure should be applied to the valve disc to force sealing surface to ensure that the medium does not leak.
  • Flange Double Offset Butterfly Valve

    Flange Double Offset Butterfly Valve

    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 self-designed Flange double offset butterfly valve has greatly eliminated the structure Excessive squeezing and scraping between the disc and the valve seat can reduce the opening resistance, reduce wear, and increase sealing performance and service life; Flange double offset butterfly valve is mainly used in petroleum, metallurgy, water treatment, water supply and drainage and other fields.

  • Introduction of Electric Butterfly Valve

    The electric butterfly valve adopts a centerline disc structure, the valve seat and the disc are almost free of wear, and has a tighter and tighter sealing function, which can withstand the sealing requirements of high-pressure media; its structure is simple, small in size and light in weight.

  • Causes of butterfly valve failure

    The causes of butterfly valve failure are as follows:1. There are sundries on the butterfly plate and sealing surface;

  • Globe valve or gate valve for high pressure steam? Which one is better?

    Because steam is generally a high-temperature medium, butterfly valves and ball valves are not suitable, and diaphragm valves and knife gate valves are even more inappropriate. The most commonly used on-off valves for steam are gate valves and globe valves.

  • Gate valve characteristics

    The body is made of high-grade ductile iron, which is about 20%~30% lighter than traditional gate valves, and is easy to install and maintain.

  • The function of check valve

    Check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium. The check valve is an automatic valve whose main function is to prevent the backflow of the medium and prevent the pump and drive motor from reversing. and the release of container media.

  • Direction of Valve Installation

    Many valves are directional in installation, such as globe valve, throttle valve, pressure reducing valve, check valve, etc. if the position is reversed, the service effect and service life of the valve will be affected (such as throttle valve), or it will not work at all (such as pressure reducing valve), or even cause danger (such as check valve). General valve, there is direction mark on the valve body. If not, it should be correctly identified according to the working principle of the valve.
