Oversized Resilient Seated Gate Valves


Oversized gate valve is made of high quality ductile cast iron or cast steel with high strength, light weight and precise dimensions. The disc is replaceable. And the valve is gear operated and can open or close the valve easily by one man, at the same time it can be with opening indicator according to the client's requirements, or be with electric or pneumatic actuator. It's sealing and anti-rust function is very good. And it is reliable with long life. It can be installed vertically or horizontally and used widely in the system such as feeding and draining, sewage treatment, construction, mining, metallurgy, electric power plant etc.
