Needle Valve Manufacturer

Valvesonly Europe is well known for Needle Valve Manufacturer in Italy. A needle valve is a type of valve that is used to control the flow of fluids (liquids or gases) with a high degree of precision. It is named after its thin, needle-like stem, which moves up and down within a narrow, cylindrical flow passage. The stem controls the opening and closing of the valve by moving a tapered seat into or away from the flow stream. The smaller the flow opening, the more precise the control of the flow rate. The stem is usually operated manually, by turning a handle attached to it, but it can also be automated using actuators.

The working principle of a needle valve is based on the movement of a needle-shaped stem within the valve body. The stem has a tapered tip that regulates the flow of fluid by coming into or moving away from a matching tapered seat in the valve body. When the stem is rotated in one direction, it moves the needle tip away from the seat, allowing fluid to flow through the valve. When the stem is rotated in the opposite direction, the needle tip moves toward the seat, gradually restricting the flow until it is completely closed.

The precise flow control provided by needle valves makes them ideal for applications where a high degree of accuracy is required, such as in laboratory experiments, process control systems, and other types of industrial and scientific applications. Additionally, needle valves are often used in applications where it is important to maintain a consistent flow rate even as pressure and temperature conditions change, such as in systems for gas or liquid delivery.

Valvesonly Europe is the prime Needle Valve Manufacturer in Italy and is famous for its premium quality products which come in various materials and designs. We aim to make customers happy and provide them with leakproof and lengthy lifetime products as per their demand.

Types of Needle Valves:

• Motorized Needle Valve- use electric or pneumatic actuator for operation
• Angle Needle Valve- turn the output by 90degrees instead of in-line

Advantages of Needle valve:
