Ultra short structure length, saving material, can make the overall weight of the pipeline system is greatly reduced. The effective space is small, can effectively support the strength of the pipe, can reduce the possibility of pipe vibration. The selection of austenitic stainless steel gate, corrosion resistance is greatly improved, can effectively prevent the leakage caused by the leakage of the seal. Equipped with a rotary electric device, the valve plate up and down motion, realize remote control valve to open or close. The diameter range: DN50~DN800, temperature: less than or equal to 100 DEG C, used in sewage, papermaking, chemical, coal, sugar and other fields, especially suitable for papermaking industry to make adjustment and throttle in the pipeline.
