Manual ductile iron buried (long rod) seated gate valve
characteristic
The application of buried (extended rod) elastic seat seal gate valve adopts the design scheme which can avoid maintenance free and extend the valve stem.
It can avoid the high cost of valve well and the huge investment brought by many road reconstruction and valve replacement, beautify the road environment, resist rolling and avoid accidents caused by the loss of well cover.
The valve rod can be flexibly customized according to the valve well.The valve switch display is set on the top of the valve stem.
The signal transmission device can be installed on the extended rod elastic seat seal gate valve, and the valve misopening locking device can be installed.
Notes for installation of buried (extended rod) elastic seat seal gate valve: the connection between gate valve and pipe shall be natural and smooth to avoid bending force.
The expandable pipe shall be corresponding to space to ensure reliable installation of buried (extended rod) elastic seat seal gate valve and keep the same horizontal ground surface. In order to facilitate future operation, the distance between expansion rod and well chamber shall be 5-10 cm.
