Ductile iron service valves are designed for underground isolation and utility house connections in drinking water and neutral liquid networks. Manufactured with an EN-GJS-500-7 ductile iron body and bonnet, these valves provide reliable shut-off, low operating torque, and corrosion protection for buried infrastructure. Coated with a minimum 250 µm RAL 5015 powder epoxy layer, they feature a fully vulcanized EPDM wedge and stainless steel stem for maintenance-free operation across PN16 utility installations.
