Fluorine-butterfly cut-off Industrial Valves open-close part is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, lifting lever ( rod and hand wheel lifting) And lift rotating lever ( Hand wheel rotating lifting with the valve stem and nut in the body) 。 Globe valve used throughout close tu, don't allow to adjust and throttling. Fluorine-butterfly cutoff valve

fluorine-butterfly cut-off valve performance characteristics 1, compared with the gate valve, globe valve structure is relatively simple, manufacture and maintenance are convenient. 2, sealing surface is not easy to wear, abrasion, good sealing, long service life. 3, when opening and closing valve stroke lesser, opening and closing time is shorter, smaller valve height. 4, disc and stem design structure, compact structure, the use of safe. 5, the structure of the cut-off valve has three forms: cut-through, once-through, Angle type, straight through the most commonly used, type can be installed in the corner of the pipeline system, once-through flow resistance is the smallest of globe valve. 6, can according to user needs with pneumatic, electric devices, meet the needs of the remote control and programmed control. 7, replacement parts lining materials can be used all kinds of medium. Scope of this valve fluorine-butterfly cut-off valve is dedicated to control general corrosive medium, the valve body cavity surface covered with a selection of all kinds of rubber, suitable for different working temperature and fluid in the tube, with high strength, good corrosion resistance characteristics. Applicable temperature: & le; 85℃,勒; 100℃、≤ 120℃（ According to the lining material) Pressure rating: PN ( MPa） 1. 01. 6
