FN1-BV1W-2L (Wafer Butterfly Valve–Handle Operation)
Butterfly valve has the advantages of simple structure, small volume, heavy light, small installation size, fast switch.
1. The butterfly plate adopts frame structure with high strength, large flow area and small flow resistance.
2. It can be used in different media as long as the sealing material of sealing valve seat is replaced.
3. The valve structure, flexible operation, labor saving, convenient.
General Use: Water,seawater,gas, pressurized air, acids etc.
