Extension rod gate valve

Extension rod gate valve,also called direct buried retractable gate valve is also called the buried soft-sealed gate valve. The valve can be buried directly in the ground without building a manhole, which reduces the area of ​​road excavation; the extremely small well chamber can keep the road beautiful, reduce the construction difficulty, and reduce the project cost. During the construction process, the retractable type can be adjusted arbitrarily in a large range according to the distance between the buried depth of the valve and the ground, and the fine-tuning fixed type can be adjusted slightly on site. The direct buried soft-sealed gate valve has the advantages of no leakage and maintenance-free in long-term use, and can also effectively prevent others from opening and closing the valve at will and stealing the manhole cover.
