Introduction to Needle Valve, its Applications and Features

Multiport valves as well as needle valves separate the process from measuring instruments such as switches, pressure gauges, or transmitters. By closing this particular device, the instrument can bedismounted safely for services like replacement and recalibration. When there is the option for vent connection available, the instrument can be vented to the atmosphere with the help of the needle valve. When the standard version is already present, the multiport valve can be equipped with a couple of extra connections. With the aid of the non-rotating spindle tip, the sealing element’s wear can be greatly reduced. This can allow for a considerable increase in the service life. By using the valve’s blow-out proof design, the working safety can be greatly enhanced, especially when there is any kind of high pressure loading application.

Applications of the needle valve 

²  Vent pressure and shut off measuring device

²  For liquid and gaseous aggressive media that are relatively less viscous in nature

²  Process industry — Oil and gas industry, chemical and petrochemical industries, power generation, and wastewater industries

Special features of the needle valve

²  Low-wear design as there is a non-rotating spindle tip present in the bonnet

²  Highly smooth operation of the handle of the valve even when at high pressure

²  Much improved safety as a blow-out proof bonnet design is being used

²  Valve seat which is tested for leak tightness according to the BS6755 / ISO 5208 leak rate A

²  Client-specific combination of instruments and valves and on request
