The product is widely applicable to various working conditions in fields such as power, chemical engineering, metallurgy, chemical fiber, pharmaceuticals, environmental protection, etc. It is one of the most widely used and common valves in pipeline systems.

Product Features

Stable Sealing: The sealing principle of a gate valve is to achieve a seal through the tight fit of the two sealing surfaces on the wedge-shaped gate. The sealing performance is stable and reliable.
Low Resistance: The fluid resistance is small, the opening and closing moment of force is low, and it is relatively effortless to operate.
Unrestricted Flow: The medium flow direction is unrestricted, without disturbing the flow or reducing the pressure.
Customizable: Materials of the main body, inner components, packing, gaskets, and fasteners can be tailored to user requirements or specific working conditions.
