Gate valveThe gate valve is mainly divided into the concealed stem gate valve and the exposed stem gate valve. The concealed stem gate valve is cast from high-quality ductile iron, featuring high strength, light weight, and precise geometric dimensions. It uses the elastic deformation of the gate to achieve a good sealing effect. The valve has significant advantages such as overall rubber lining, corrosion resistance, durability, good elastic memory, and long service life. It can be equipped with a turbine drive, pneumatic actuator, and electric actuator device. It can be widely used in water supply, construction, system pipelines, etc., as a regulating and cutting off water flow device. The exposed stem gate valve, in addition to having the advantages of the concealed stem gate valve, can also intuitively display the valve opening, and it is quick and reliable to open and close. Therefore, it is often used in fire protection and working systems, and is generally installed at a higher position above the ground.
