Instrumentation Needle Valves are versatile solutions for flow metering, as bleed valves or shut-off applications. The versatile components are a good choice for control and instrumentation solutions. The accurate needle valves market offers many types of needle valves – and the options yet increase. Finding and selecting the proper needle valve for a specific given application is therefor of crucial importance. If an improper valve is installed, the consequences can be quite drastic: Ranging from failure to comply with safety and industry standards via product contamination due to peeling of the valves coating materials up to a complete failure of the production process – any of the factors will ultimately lead to higher production costs due to frequent replacements of low-quality valves.
In fact, a single valve can make or break a whole process plant's performance record. It is therefore crucial to understand the set-up and functionality of instrumentation needle valves to ensure a proper functionality. The problems with valve malfunctioning can be avoided only if the correct parameters re considered when selecting a component.
These include: ● Considering the specific application for your valve installation (pressure, temperature, media, flow, etc.). ● Considerations for using panels mounted needle valves. ● Sealing methods for leakage and wear prevention. ● Wear compensation (durability)
