Duvalco resilent seated gate valves are non-rising spindle designs with the ductile iron gate fully encapsulated in EDPM rubber. The smooth invert eliminates dirt pockets that can prevent proper closing of the valve and accurate rubber molding ensures low closing torques and effective seal. The entire valve is coated with fusion bonded epoxy for a high level of corrosion protection, with all materials certified for potable water use.
