Different valves find their way into a variety of applications. Among common usage are valves implemented in factories and other industrial and commercial facilities for flow control. Flow control, in its most simple explanation, the action of regulating the speed of a liquid in a hydraulic or another system. Flow control valves are available in several options. The most common types are:
- Needle
- Fine metering
- Quarter turn plug
- Rising plug
The needle flow control valve is popular for the precise regulation of flow rates.
What Is A Needle Valve?
A needle valve has these major distinguishing features a.
- Small port
- Threaded needle-shaped plunger
- Tapered pin
The valve sits on the end of a fine-threaded screw. The turning of the screw and the retraction of the needle-like plunger permits the flow between the plunger and the seat. The slow and exacting turning of the screw ensures incremental and precise flow rates.
Needle Valve applications
Needle flow control valves find application where the following conditions are evident:
- The flow rate is low
- It must be constantly calibrated
- The flow rate requires maintenance for an extended period
- The flow requires gentle adjustment but precise control
Unlike other valves, the needle variation is particularly adapted for use in delicate or sensitive gauges. This type of gauge may suffer damage if the flow surges. The installation of a needle flow control valve prevents this from happening.
Needle Valve Flow Control
If you are looking to exert a basic control of the hydraulic flow of a system, an economical solution is a needle valve flow control. This option is ideal for general control of a flow rate that must remain constant over a lengthy period. Companies might find them best to use in carburetors, the filling of gas lasers where precision is essential. This is applicable to both the stoppage and the flowing of a liquid substance.
