The difference between the butt-clamp butterfly valve and the flange butterfly valve
I. Connection Method and Convenience
1、Clamping Butterfly Valve Using clamping connection, usually connected by bolt clamping, without additional flange and a lot of bolts. Easier installation and maintenance, can be quickly installed and disassembled, saving time and cost. It is suitable for occasions with limited space or tight piping position.
2、Flange Butterfly Valve Using flange connection, the valve body flange is connected to the pipeline flange through bolts. Installation and maintenance are relatively cumbersome, requiring additional flanges, bolts and nuts. The connection is more stable, suitable for the occasions with higher requirements on connection strength.
Ⅱ, the applicable scene and performance
1、Clamping butterfly valve Suitable for general low and medium pressure and small diameter piping system. The cost is relatively low, suitable for projects with limited budget. Although the sealing performance is slightly inferior to flange butterfly valve, it can still meet the demand in general application. Widely used in industrial pipeline control, building water supply and drainage systems, automation control systems and water supply and drainage treatment and other fields.
2、Flange butterfly valve Suitable for high temperature, high pressure and large calibre piping system. Higher cost, but better sealing performance, can withstand higher pressure and temperature. In special circumstances can be added blind, increase the flexibility and safety of the system. Widely used in petrochemical, food and beverage, iron and steel metallurgy, environmental protection engineering and central heating systems and other areas with high requirements for fluid control.
