Subsea Needle Valves, 15SN and 20SN Series

Ideal for deep-sea applications

15SN and 20SN Series Subsea Needle Valves feature a high-tensile 316 stainless steel body, supporting pressures up to 20,000 psig (1,379 bar) and water depths of up to 13,800 ft (4,200 m), making them ideal for deep sea applications. The two-part spindle assembly includes a non-rising upper stem, providing an advantage for ROV operation. A non-rotating lower stem ensures positive, non-galling shutoff. Metal-to-metal seating delivers reliable shutoff, an extended stem/seat service life for abrasive flow, excellent corrosion resistance, and durability for repeated on/off cycles. Available in 2-way straight and angle flow patterns, with various connection types and sizes.
