Description

Needle valves and multiport needle valves separate the process from measuring instruments such as pressure gauges, switches or transmitters. By closing this valve the instrument can be safely dismounted for service work like calibration or replacement. Versions with an additional vent connection are able to vent the instrument to the atmosphere by means of the needle valve. The multiport needle valve is already equipped with two additional connections. These can be used either as vent connections or for the connection of additional 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.

For further approvals, see page 8

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.

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

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
