2 Inch Butterfly Valve Features:
⊙ Adjust tightness
Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures
best performance of adjusting the compression of sealing.
⊙ Sealing reliable
Body and disc made of ductile iron which promote the impact resistance and pressure-bearing
capacity, sealing ring made of rubber and valve seat’s sealing surface is conical shaped, make the
sealing capacity more reliable.
⊙ Excellent corrosion protection
Inside electrostatic epoxy resin power coating or vitreous enamel(upon request), outside electrostatic
epoxy resin power coating.
⊙ Reliable health nature
Epoxy resin power is up to the health standard.
