WIKA IV1 Needle Valve

About this product

Product Description Needle valves and multi port needle valves separate the process from measuring instruments such as pressure gauges, switches, or transmitters. By closing this valve, the instrument can be safely disassembled for maintenance work such as recalibration or replacement. The version with additional exhaust connection can release the instrument into the atmosphere through a needle valve. The multi port needle valve is equipped with two additional connections. These can be used as ventilation connections as well as for connecting other instruments. Through the non-rotating spindle tip, the wear of the sealing elements is reduced. This results, particularly with frequent opening and closing, in a noticeable increase in the service life. Through the blow-out proof design of the valve, working safety is improved, especially in applications with high pressure loading. The natural gas design, model IV1N is available with a metering valve that enables both, instrument shut-off and flow control. Special Features Low-wear design due to non-rotating spindle tip in the bonnet. Low torque and smooth operation of valve handle even at high pressure. Enhanced safety due to blow-out proof bonnet design. Valve seat tested for leak tightness per BS 6755 / ISO 5208 leak rate A. Customer-specific combination of valves and instruments (instrument hook-up) on request. Applications Shut off and vent pressure measuring instruments. For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive environments.
