Manhole valve, manhole cover or manhole cover is a valve that is placed on all types of sewer manhole, electrical manhole and telecommunication manhole. Sewer cover is installed to prevent objects and people from falling into the manhole. One of the most important infrastructures in different sectors is the sanitary wastewater treatment system, which is intended for the passage of wastewater, and to do this, large diameter pipes called sewage manholes are used. To reduce the risk and prevent people and various objects from falling into the pipe, it is covered with a manhole valve and the need to use it is felt more when these pipes are located in the middle of passages and busy neighborhoods.
