Z41H forged steel flange gate valve

1. Structure and characteristics

The closing part of the Z41H forged steel gate valve is a gate, which is a valve whose gate moves along the vertical direction of the channel axis. It is mainly used to cut off the medium in the pipeline, that is, fully open or fully closed. It is not suitable for adjusting the flow rate and conveying mud medium. It has the advantages of small fluid resistance, small torque required for opening and closing, and simple structure. Forged steel gate valves are suitable for cutting off or connecting pipeline media on small-diameter pipelines in various working conditions such as petroleum, chemical, and thermal power plants. Features: Small fluid resistance, wide applicable pressure and temperature range, unlimited medium flow direction, and good sealing performance.
