Double Disc Gate Valves

The double-disc (parallel) gate valve seals with two parallel discs forced apart against the seats by a wedging mechanism as the valve closes, giving low-torque, bubble-tight isolation without the seat drag of a solid wedge. Because the discs part from the seats before travelling, seat wear is low and closure remains reliable over many cycles. They are made in cast iron and steel with resilient or metal seats. Provide the bore, pressure rating, medium and connection so we can propose a suitable valve.
