PZ73H-10C electric knife gate valve with ultra-short structure length saves material, which can make the overall weight of pipeline system greatly reduced. Occupy little effective space, can effectively support the strength of the pipeline, can reduce the possibility of pipeline vibration. Gate selection of austenitic stainless steel, corrosion resistance is greatly improved, can effectively prevent seal leakage caused by gate corrosion. Equipped with a multi-turn electric device, so that the valve plate for up and down linear movement, to achieve remote control of the valve open or close, the valve body material is cast steel, stainless steel.
