# Installation Notes for Butterfly ValvesInstallation Environment:Suitable for indoor and outdoor use. Use corrosion-resistant materials for corrosive or rust-prone conditions. Consult the manufacturer for special applications.Installation Location:Install in safe, easy-to-operate, inspect and maintain areas.Ambient Conditions:Temperature: -20℃ ~ +70℃, Humidity ≤90%RH.Check the nameplate to ensure suitability for working conditions.Butterfly valves cannot withstand high pressure differences. Do not open or operate under high differential pressure.Before Installation:Clean dirt, scale and oxides in the pipeline.Ensure medium flow direction matches the arrow on the valve body.Installation:Align pipe centers, keep flanges parallel and tighten bolts evenly.Avoid excessive piping stress on pneumatic actuators.Provide proper support according to valve size and weight.# Maintenance NotesRoutine Inspection: Check for leakage, abnormal noise and vibration.Regular Inspection: Inspect for leakage, rust and seizure; clean and remove residues.Overhaul: Disassemble periodically, clean parts, remove foreign matter, replace gaskets and packing, repair sealing surfaces. Conduct hydrostatic test before reuse.If leakage occurs on pneumatic butterfly valves, keep hands away before confirming safety.Tianjin Kaivis Valve Manufacturing Co., Ltd.is a professional manufacturer integrating R&D, production, installation, sales and wholesale of check valves, butterfly valves, gate valves, ball valves, ventilation butterfly valves, blind valves and imported valves.
