Needle Valves Open the Valves of Performance
Small things make big differences: Although needle valves are comparably simple in construction, the effects of an ill-suited valve selection can be quite drastic. Problems, ranging from issues with standard compliance to contamination or even process failure, are typical consequences of low quality or simply inapt valves. The benefits of needle valves, on the other hand can be quite big — if the proper component is selected.
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.
- 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).
What Is an InstrumentationNeedle Valve?
Needle valves are used for on-off service and the rough flow control of liquids or gases in pipes and tubing systems. These valves can be adjusted to enable higher or lower flow rate, using a needle which covers the valve opening by different degrees. This allows the user to control the size of the opening to regulate the fluid flow. Due to this design’s versatility and clear construction, a user can choose from a variety of valves for a given application.
