Wedge-type open stem single steel gate valve

a. Generally only suitable for fully open or fully closed, and cannot be used for adjustment and throttling;
b. Generally used in situations where there are no strict requirements on the external dimensions of the valve and the use conditions are relatively harsh, such as high temperature and high pressure working media, where the closing parts are required to ensure long-term sealing, etc.;
c. When using conditions requiring reliable sealing performance, high pressure, high-pressure cut-off, low-pressure cut-off, low noise, cavitation, and vaporization phenomena, high-temperature media, low temperature, and cryogenic temperatures, it is recommended to use wedge gate valves. In petrochemical, petroleum, and urban construction It is widely used in water supply engineering, sewage treatment engineering, the chemical industry, and other fields;
d. Suitable for working conditions requiring small flow resistance, strong flow capacity, good flow characteristics, and strict sealing;
e. Suitable for high temperature and high-pressure media such as high-temperature steam, high temperature and high-pressure oil;
f. Suitable for low-temperature and cryogenic media such as liquid ammonia, liquid hydrogen, and liquid oxygen;
g. Suitable for low-pressure and large-diameter fields such as water supply projects and sewage treatment projects.
