Product Overview
- Non-rising stem resilient seated gate valve utilizes the deformation compensation effect of the overall rubber coating of the gate valve to achieve a good sealing effect, overcoming the problems of poor sealing, water leakage, and rusting common in ordinary gate valves, and more effectively saving installation space. It can be widely used in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, pharmaceutical, light textile, electric power, shipbuilding, metallurgy, and energy systems as a regulating and shut-off device.
