What is Needle Valve?
A Needle Valve is one category of valve having small port and a threaded needle shaped point at the end of valve stem that is referred as plunger. The function of this valve is to allow accurate flow regulation; but, these types of valves are usually suitable in the applications that containing comparatively lower flow rates. The Needle Valve controls the flow in both directions so it is bi-directional control valve also.
Needle valve can operate both manually and automatically, in manually it has handwheel that operates the plunger, when handwheel in turn-on direction the plunger would open and allow flow to pass. When handwheel in other direction plunger moves to seat and decrease flow respectively and will stop. Automatic needle valve connected to hydraulic motor which adjust plunger position according to timer and make automatically open and close the valve. However, in both condition needle valve provides the precise regulated flow. Needle valves are usually made of stainless steel, bronze, brass, or metal alloys. It’s important to choose a needle valve made with the material that’s best suited for the service you need.
Utilization of Needle Valve
Needle valves are commonly used to control perfect flow rate and protect delicate gauges from damage due to sudden pressure excess of liquids and gases. They’re ideal for systems using lighter and less viscous materials with low flow rates. Needle valves suit in low-pressure, less viscous material and having low flow rate hydraulic systems, chemical processing, and other gas or liquid services.
However, needle valve used in almost in all industries where low flow rate is needed. Here list of some industries where prominent utilize of needle valves
- Oil and gas in gas or liquid dispensation
- Power generation
- Cooling
- Instrumentation control
- Automatic combustion control systems
