F4 elastic seat gate valve QT400 water pressure PN16 specification DN100 for water delivery
Gate valve refers to a valve whose closing member (gate) moves in
the vertical direction of the channel axis. It is mainly used to
cut off the medium on the pipeline, that is, fully open or fully
closed. Under normal circumstances, gate valves cannot be used to
adjust the flow, nor are they generally used in pipelines for
conveying medium such as mud. According to the temperature and
pressure of the working conditions, the gate valve of the matching
material can be selected.
It has the advantages of small fluid resistance, small torque
required for opening and closing, relatively simple shape and
structure, and good manufacturing process, and can be used in
pipelines where the medium flows in both directions. When fully
opened, the sealing surface is eroded by the working medium.
smaller than the globe valve.
