Product Overview
Machined from forged bar, our 'ID' Type Double Block and Bleed Valves feature two inline ball pattern primary and secondary isolating valves and a heavy-duty needle vent valve. With a range of different operating temperatures and configurations, Double Block and Bleed Valves from Oliver Valves are the superior market leader. Our Double Block and Bleed valves provide Soft or Metal seating, with 10mm, 14mm, or 20mm bore isolation valves for many applications without having to resort to traditional single isolate ball valves.
The needle valve is supplied as standard with a non-rotating tip to allow linear closure while eliminating galling. Our standard 'D'Type DBB range from ¼" up to 1". DBB Valves are available in Stainless Steel, Carbon Steel, Duplex, Super Duplex and many other materials on request. All Oliver Valves products have material traceability and pressure test certificates to BS EN 10204 3.1.
