The model HPNV cryogenic needle valves have been developed for high pressure applications of 15,000 to 60,000 PSI (1,034 to 4,136 BAR). The valve is particularly suitable for control panels, where the space is restricted, or for test benches. Special bonnet designs suitable down to -196°C are available.



The non-rotating valve spindle prevents seizing and scoring, even if the valve is rarely opened or only partially closed. With the blow-out proof design of the valve, working safety is ensured, especially in applications with high pressure loading and frequent pressure cycles. The valve can be fully opened/closed with only 5 turns.



The risk of unintentional loosening of the bonnet is minimised by a mechanical stop for the handle. Quick assembly and disassembly of the handle is possible thanks to the self-centring system. The valve design and high-quality sealing materials ensure long operating times and high tightness.



On request, WIKA offers the professional assembly of valves and pressure measuring instruments and also other accessories into a ready-to-install solution, also known as an instrument hook-up. To ensure the performance of the complete system, an additional leak test is carried out on the instrument hook-up.



Applications:

  • Oil and gas, chemical industry, machine building and automation
  • For injection systems, test benches, hydraulic power packs, blow-out protection
  • Blasting/cutting with water, high-pressure cleaning


Features and Benefits:

  • Low-wear design due to non-rotating spindle tip in the bonnet
  • Low temperature design down to -196°C available
  • Low torque and smooth operation of valve handle even at high pressure
  • Leak-tested tightness in accordance with BS6755 / ISO 5208 leakage rate A
  • Large selection of materials and configurations available
  • Customer-specific combination of valves and measuring instruments (instrument hook-up) on request
