Structure and Working Principle
Structure: Stainless steel needle valve is mainly composed of valve body, valve stem, valve core, valve seat, packing, gland and other components. The valve core is needle shaped and cooperates with the valve seat to achieve sealing.
Working principle: By rotating the valve stem, the valve core is driven to move up and down, thereby changing the gap between the valve core and the valve seat, achieving precise control or complete cut-off of the medium flow rate. When the valve core is tightly attached to the valve seat, the valve closes, preventing the flow of the medium; When the valve core rises, the medium can flow through the gap between the valve core and the valve seat.

Good sealing performance: The contact area between the valve core and valve seat of the needle valve is small, and the sealing pressure is high, which can effectively prevent medium leakage and maintain good sealing even under high pressure.
Strong pressure resistance: Stainless steel material has high strength and hardness, and can withstand high pressure. The nominal pressure can generally reach 1.6MPa-32.0MPa.
Accurate flow control: Due to the needle like structure of the valve core, when the valve is opened, the channel area through which the medium passes is small, which can achieve precise adjustment of small flow media and is suitable for situations where precise flow control is required.
Long service life: Stainless steel has good corrosion resistance and wear resistance, is not easy to rust and wear, and after the sealing surface is damaged, only vulnerable parts need to be replaced to continue use.

Nominal pressure: 1.6MPa-32.0MPa.
Applicable temperature: -40 ºC -+540 ºC.
Applicable media: Suitable for various non corrosive or corrosive media such as oil, water, gas, etc.
Connection methods: Common ones include welding, sleeve threaded connection, flange connection, etc.

Application field
Petrochemical industry: used for flow control and cut-off of chemical raw materials, oil products, gases and other media, such as at the inlet and outlet of chemical pipelines and reaction vessels.
Electric power industry: used in instrument measurement pipelines, steam pipelines and other systems of power stations to measure and control parameters such as pressure and flow rate of media.
Metallurgical industry: It can be used for the transportation and control of gas media such as oxygen and nitrogen, as well as the flow regulation of oil and liquid in hydraulic systems.
Pharmaceutical industry: In the fluid delivery system of drug production, it is used to precisely control the flow of drugs, gases, and other media to ensure the accuracy and stability of the production process.
