API standard gate valve is a fully open or fully closed valve. The API standard gate valve controls the medium flow in the pipeline. When the disc is closed, it prevents the medium flow. When the disc is open, the medium can pass through the valve. API standard gate valve can only be fully opened or fully closed, not half opened.

Flanged Type Gate Valve is a widely used valve, which mainly cuts off the pipeline; the flange connection method is stronger and the performance in engineering is more stable. The Flanged Type Gate Valve produced by MST is of high-end quality, widely used, excellent material, high sealing design, can produce national standard, American standard flanged gate valve, and has received unanimous feedback from users

Large diameter gate valve is a kind of valve which is opened and closed by the vertical movement of ram.

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.

Cryogenic gate valve is suitable for methane, liquid natural gas, ethylene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, liquid hydrogen and other low temperature media.

Dual Plate Wafer Check Valves have been the preferred choice due to their proven reliability and low pressure drops. MST produced Dual plate wafer check valves are tested to API 598 and must meet or exceed all applicable API, ANSI and ASTM Standards.
