Subsea Needle Valves

Subsea Needle Valves – Technical Data

• Working pressure up to 20,000 psig (1379 bar)
• Maximum external pressure: 6,000 psig (414 bar)
• NBR O-ring for operation from -10 to 250F (-23 to 121C); other O-ring materials available
• High tensile 316 stainless steel for valve body
• Standar stem seal material: PTFE
• Available to NACE MR0175
• Using a two-part spindle assembly with a non-rising upper stem, it is of great advantage when being used with ROVs
• Non-rotating lower stem to ensure positive non-galling operation suring shut-off
• Packing located under stem threads
• Metal-to-metal seating to ensure ideal shut-off, longer stem/seat service lifetime for abrasive flow, excellent corrosion resistance and greater durability for repeated on/off cycles
• Reliable packing gland locking device
• Wide selection of tube and pipe end fittings available
• 2-way straight and angle flow patterns available
• Orifice size: 0.203”
• Rated Cv: 0.75
• Maximum water depthL 13,800 ft. (4200 m)
