Applications of Electric Needle Valve

A

The needle valve is also known as the plunger valve, and they are the flow controlling valves that are used to control the pressure & flow rate of the fluids inside the pipeline. The adjustment process of the electric needle valve is so fine, which provides the exact precise control of the flow of fluids. Generally, these digital flow control valve‘s are used for the management of the too low & too high pressure to a suitable pressure of fluids. In this article, we are going to mention some of the common applications of needle pressure-controlling valves.

The function of the Needle Valve:

The electric needle valve closes or opens the passage of fluids in between the inlet & outlet because of the movement of the tapered point needle normal towards the flow direction. The needle is connected directly with the stem or plunger. The stem or plunger is further connected to the handle that converts the rotational motion into to & fro motion with the ease of the fine internal thread of the bonnet.

The rotational motion offered to the handle is the fine up & down movement stem takes place and the opening & closing of the orifice. The locking nut is connected with the bonnet’s top to prevent the entire unscrewing of the plunger from the internal thread of the bonnet. When the needle goes down, it comes in contact with the seat of the flow control solenoid valve, and hence it provides a leakage-free closing of the fluid in the pipeline. The bonnet is connected with the housing of the electronic valve via the screw system.

The actuation of the electric needle valve is managed with the rotation of the handle by it could be automatically. The needles of the valve are usually operated with the help of an electric motor. This motor precisely controls the stem position inside the housing of the pneumatic needle valve depending on the external requirements.

Applications of Needle Valve:

One of the most common uses of the needle is to manage the flow & protect the fragile from any damage from the abrupt pressure of surges of fluids. The electronic needle valve is ideal for those systems that use the lighter & less viscous materials along with the less rates of flow. The electric needle valve is utilized in the low-pressure chemical processing, hydraulic systems, and other services of liquids & gasses.

Another perk of the plunger valves is that they are capable of applying the elevated temperature & oxygen service depending on their materials. The flow control needle valve is made up of stainless steel, brass, and bronze. Opting for an electric needle valve made with the material that perfectly suits the service you need is mandatory. In this way, one can ensure the long lifespan of the electronic flow control valve, and it makes the system run smoothly & safely.
