Oliver F Type Double Block & Bleed Valve – Flanged, Forged Duplex Body
Rp123000.00
The F Type Double Block & Bleed (DBB) Valve is a compact forged-body manifold integrating three in-line ball valves—two for isolation and one for venting. Designed for high-integrity isolation, the F Type configuration is ideal for applications where space and weight are limited but full-bore flow and robust operation are required.
Manufactured from a single-piece forged body with controlled grain flow, this valve type provides enhanced mechanical strength and leak-tight performance. It is particularly suited for offshore and process-critical environments and is available with a variety of body and trim materials, including Duplex stainless steel, with optional fire-safe and NACE compliance.
