Subsea Needle valve, Non-Rising, Non-Rotating Stem
*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.
Parker's non-rising, non-rotating stem needle valve designed specifically to deliver smooth, low-torque performance in subsea applications. Featuring metal-to-metal seat for bubble-tight shut-off, longer stem/seat life, greater durability for repeated on/off cycles and reinforced PTFE/PEEK chevron packing below stem threads for dependable stem and body sealing. This subsea needle valve incorporates additional o-ring seals, which prevent the ingress of sea water into the valve which could adversely affect the operation of the valve as well as contaminate the process fluid.
The uni-directional valves are available in a range of corrosion-resistant alloys and are suitable for equipment located at depths down to 3,050m.
The valves are designed to facilitate operation either manually or by a Remotely Operated Vehicle (ROV).
Parker's subsea needle valves have been designed to meet or exceed the rigorous qualification test requirements of API 17D PSL 3/3G. The design's structural integrity and performance have been confirmed by Lloyds inspectors witnessing the API 17D valve design validation protocol. This was carried out on the base 316SS model and included the API 6A PR2F PSL3/3G uni-directional testing protocol as well as the API 17D Hyperbaric test protocol.
Markets:
• Upstream Oil & Gas
Features/Benefits:
• Three-piece, bolted bonnet construction
• Uni-directional flow
• Metal-to-Metal seating achieves bubble-tight shut-off, longer stem/seat life, greater durability for repeated on/off cycles and excellent corrosion resistance.
• Double O-ring stem seal prevents sea water and silt ingress to any threaded or rotating parts
• Additional bonnet seals engineered to prevent water and silt ingress to any threaded or rotating parts
• Low friction, pressure assisted PTFE/PEEK shaft seal increases cycle life and reduces operating torque. The packing is situated below stem threads provides dependable stem and body sealing.
• Non-rising, non-rotating stem protects against stem galling and seat damage
• Designed to accept multiple types of tube and pipe end connections
• Available in a variety of corrosion-resistant materials
• Designed and tested to API 17D/API 6A standards
Applications:
• Subsea Hydraulic Manifolds
• Subsea Control Umbilicals
• Subsea Wellheads and Control Packages
• Chemical injection
• DBB, bleed, vents, test lines
