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.
Product Features
Underground Soft Seal Gate Valve is a soft seal gate valve with a drive lever installed on it, and the user opens and closes the gate valve by turning the drive lever on the ground. The advantages are as follows:
- Easy installation: Can be directly buried underground without the need for constructing manholes.
- Easy operation: Open and close using the ground-level transmission rod.
- Ground subsidence will not affect the normal operation of underground soft-seal gate valves.
- The socket-and-spigot connection effectively mitigates the adverse effects of ground subsidence on the valve.
