Ball Valves
Ball valves are the main part of Valland’s core business. The range covers four families, all fully engineered in-house at the Piantedo (Italy) plant: trunnion mounted ball valves (side entry), floating ball valves, top entry ball valves and top entry rising stem ball valves.
Valves are designed to API 6D, API 6DSS or API 6A, with body design per ASME B16.34 or ASME VIII Div. 1 & 2. They can be supplied with cast or forged body and closures, with a wide choice of material grades — from carbon steel to duplex, super duplex, nickel alloys and titanium — and end connections including flanged, butt-weld, compact (Norsok L-005) and hubbed.
Valland ball valves can be engineered for double block and bleed (DBB) and double isolation configurations (DIB-1 and DIB-2), for cryogenic service and for subsea installation. SIL certification up to SIL 3 has been achieved for trunnion mounted and top entry ball valves. Finite Element Analysis of the design is available on request and is performed entirely in-house.
Reference projects include side entry trunnion and floating ball valves for the AkerBP Hod field development (Norway), a 182-valve manual package for the Santos Barossa FPSO (Australia) and top entry ball valves for the AkerBP Hugin A riser application.
