Water Pressure Ductile Iron Gate Valve QT400 DN100 PN16 Wastewater

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.
