MZ45X underground soft seal gate valve is also called buried gate valve. It can be buried directly into the ground without the need to build manholes, which reduces the area of roadway excavation; the very small manhole chamber can keep the roadway beautiful, reduce the difficulty of construction, and reduce the cost of the project. Can be widely used in water, sewage, construction, petroleum, chemical, food, energy systems and other fluid pipelines as a regulator and interceptor.
