GB VERTICAL CHECK VALVE
The stainless steel vertical check valve uses the medium pressure to push the valve flap to open and close, realizing one-way flow and preventing backflow. When the flow is forward, the valve flap is pushed open; when the flow is reverse, the valve flap automatically closes.
Widely used in petrochemical, food and pharmaceutical, water treatment, shipbuilding, power system and other industries.
Description
Purpose
This valve is used in industrial pipelines as a device to prevent the backflow of media.
