The Needle Valve 304 with internal thread and high pressure is a type of needle valve made of stainless steel 304 material. It features an internal thread connection and is suitable for high-pressure applications.

Here are some characteristics and application scope of this valve:

Material: The needle valve is made of stainless steel 304, which offers excellent corrosion resistance and high-temperature resistance. Stainless steel 304 is a common stainless steel material suitable for a wide range of industrial applications.

Internal thread connection: The valve is designed with an internal thread connection, allowing it to be connected to pipe systems or equipment with internal threaded interfaces. Internal thread connections are typically achieved through threaded fittings or threaded flanges.

High-pressure application: This needle valve is designed for high-pressure applications and can withstand higher working pressures. The specific high-pressure range may vary depending on the valve’s specifications and manufacturer’s guidelines. It is recommended to refer to the product’s technical specifications to confirm the specific operating pressure range.

Flow control: Needle valves are commonly used in applications that require precise flow control. The rotation of the valve core enables the control of fluid on-off and flow rate. Due to the design characteristics of needle valves, they excel in low-flow and precise flow control applications.Needle-type Internal Thread Globe Valve

 

Needle valves have precise flow control capabilities and are suitable for various applications.

Here are common areas where needle valves are used:

Laboratories and research: Needle valves are widely used in laboratories and research fields for precise control of gas or liquid flow. For example, in chemical analysis, biological experiments, and fluid transfer experiments, needle valves are used to accurately control the flow of reagents and solutions.

Instrumentation: Needle valves are commonly used in various instruments and instrumentation equipment such as gas chromatographs, liquid chromatographs, flow meters, etc. They are used to control the flow of carrier gases or fluids to achieve precise analysis and measurements.

Manufacturing and processing: In manufacturing and processing processes, needle valves are used for precise regulation of fluid flow and pressure. For applications such as micro-spraying, micro-irrigation, and micro-wetting, where precise control of fluid jetting and flow rate is required, needle valves are employed.

Pneumatic and hydraulic systems: Needle valves find application in pneumatic and hydraulic systems for controlling the flow and pressure of gases or liquids. They exhibit reliable flow control performance in high-pressure or high-temperature working environments.

Chemical and petroleum industries: In the chemical and petroleum industries, needle valves are used to control the flow of various media such as liquids, gases, and steam. They are commonly employed in applications such as reaction vessels, separation equipment, furnace combustion systems, where precise control of flow and flow rate is required.
