Description

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-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.
