Products Design Features

Gate valve is one of the most commonly used cut-off valves, it*s mainly used to connect and disconnect media in pipe. The range of suitable pressure, temperature and caliber is very wide. It is widely used in water supply and drainage, gas, electric power, petroleum, chemical industry, metallurgy and other industrial pipeline which media is steam, water, oil to cut off or adjust the flow of media.

Main Structural Features

Fluid resistance is small.

It is more labor-saving when opening and dosing.

The flow direction is generally unrestricted, Easy to install.

Rational structure, reliable sealing, excellent performance, pretty appearance.
