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.
