1, fluorine-butterfly valves flange cover plate can't open, unless prepared and pipeline connection, otherwise PTFE flange surface may be caused by temperature difference, foreign bodies, knock against scratches or distortion and seal, such as moving cover board for inspection need, also must stay speed will cover plate to reset after inspection, in order to protect the PTFE flange surface. 2, fluorine-butterfly valves and piping connections, and no longer alone gasket commonly, but with dissimilar materials ( The metal surface, etc. ) Flange connect, should adopt appropriate gaskets, PTFE in order to protect the flange surface. 3, fluorine-butterfly valves in the system to use, such as leak under high temperature, shall, first of all, the system temperature down to room temperature, then find out the reason, for repair. 4, does not allow for fluorine-butterfly valves do any high temperature of welding work, so as not to cause permanent damage to the lining layer. 5, flange nut when installation should be according to the diagonal direction ( Symmetry) Uniform tightening in turn and with appropriate moment: if a flange sealing surface leakage, and leakage location nut has been lock, at this time should be relaxed leak location nut, half a circle it to side with the same torque lock again. B if the above method is still not stop leakage, PTFE should check if there is a concave and convex flange surface indentation, scratch, which can be spun yarn paper, cloth leveling to reconnect. 6, lining fluorine valve should be stored in dry and ventilated room, do not stack. 7, after repair of the lining fluorine Industrial Valves before use according to the related standard test qualified before installation. 8, manual fluorine-butterfly valves, are not allowed to use other leveraged strength to force the valve open and close. 9, there is a requirement for directional fluorine-butterfly valves when installation should pay attention to the flow of medium should be along the direction indicated by the arrows on the Industrial Valves body, and ensure the operation, maintenance is convenient. 10, long stored internally the valve seal should raise separation condition, avoid sealing surface compression permanent deformation for a long time, affect the sealing performance and service life.
