Ductile cast iron series

Butterfly valves wafer / lug type

Valves and fittings in steel and cast iron

Find out a comprehensive range of butterfly valves suitable to implement a wide variety of systems: heating and air-conditioning installations, convey of drinking water or corrosive fluids, such as sewage, brackish water and gas. Butterfly valves operate both for liquids shut-off or flow adjustment, strongly recommanded when a compact valve and reduced weight are needed. EPDM sealing and epoxy painting make this valve suitable to be used with temperatures up to +130°C. Butterfly valves, wafer type, can be manually operated with a lever (standard equipement) or gear operated, pneumatic or electric actuated.

Butterfly wafer type valves can be installed in- line between two flanges (at end-line a counter flange is required), centering is obtained thanks to built-in centering slots. All installation postions are possible.

Butterfly lug type valves are fixed to flanges through blind screws (a set for each side) which allow you to install it even at the end line without need of a counter flange. All installation postions are possible.

Cast iron butterfly valves are produced according directive 97/23/EC - also known as "PED Pressure-equipments-directive". Standard gauge design according ISO 5752, API 609 series 20. All valves can be totally inspected and all components can be replaced.
