Grooved butterfly valves feature convenient connection,quick installation and reliable sealing performance,and are widely applied in various fluid pipeline systems.They are mainly suitable for fire protection water supply pipelines,municipal water supply and drainage pipe networks,central air conditioning chilled water and hot water circulating pipelines,as well as industrial circulating water pipelines.With stable structural performance,such valves can perfectly match grooved pipe fittings,and are widely used in building water supply,HVAC systems and industrial auxiliary pipeline projects.
In terms of working conditions,grooved butterfly valves are ideal for normal temperature and normal pressure fluid transportation environments.They adapt to clean water,circulating water,cooling water and other neutral medium.Most soft-sealed grooved butterfly valves perform excellently under normal temperature working conditions,with stable opening and closing control and good flow regulation effect.They are suitable for low and medium pressure pipeline systems without strong corrosion,high temperature or high harsh working conditions.Meanwhile,they are extensively adopted in fire engineering pipelines due to their high safety and rapid maintenance performance.They are not recommended for high temperature steam,strong corrosive chemical media,high pressure ultra-high pressure pipelines and granular solid medium conveying pipelines.
