Ball, Needle, Ball DBB Valves
The Double Block & Bleed “Type V” is fully approved to be supplied to many of the world’s oil majors. At the end of the last millennium there were over 10,000 of these valves manufactured by Alco Hi-Tek and in service around the world.
All threads are generated using our in-house CNC machines. 316 stainless steel handles and trim as standard to reduce the risk of corrosion.
Materials of construction include standard grades ASTM A350 LF2 / A105, ASTM A182 F316 / F316L and ASTM A182 F51 being held for call off by our clients. This reduces the overall project delivery times dramatically. Outlets and vents are all 1/2″ NPT as standard, 1/4″ and 3/4″ are also available. Butt weld and socket weld outlets available.
