Sami Instruments, which is part of WIKA Group, is an Italian manufacturer and leader in instrumentation, piping and high pressure valves and accessories, with over 50 years of experience and know how. Their production range includes instrumentation ball valves and needle valves and manifolds, for pressures from 6.000 to 10.000 psi and with standard connections from ¼” to 1” NPT or BSPP.
WIKA HPNV – High Pressure Needle Valve
The model HPNV high-pressure needle valves have been developed for high-pressure applications of 15,000 … 60,000 psi [1,034 … 4,136 bar]. The valve is particularly suitable for control panels, where the space is restricted, or for test benches.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-centering system. The valve design and high-quality sealing materials ensure long operating times and high tightness.
