The Throttle (Needle) Valve Brass is a precision flow control component designed to regulate the flow of fluids such as air or water in industrial systems. It features a needle-style valve mechanism that allows for fine-tuned adjustment of flow rates, making it ideal for applications requiring precise control over fluid delivery.
The valve body and release ring are both constructed from brass, ensuring durability and resistance to spark generation in high-temperature or flammable environments. The main metal components feature a brass with electroless nickel plating finish, enhancing corrosion resistance and long-term performance under demanding conditions.
The valve is available in multiple connection types including metric male threads (M5x0.8) and taper pipe male threads (R1/8, R1/4, R3/8, R1/2), allowing it to integrate seamlessly with a variety of piping systems and equipment configurations.
The valve operates within a maximum pressure range of 1.0MPa and can handle vacuum conditions down to -100kPa. It is rated for operating temperatures between 0°C and 100°C (no freezing), with an extended temperature range up to 120°C under normal use conditions.
Available in a range of sizes including φ4, φ6, φ8, φ10, and φ12 mm, the valve offers flexibility for different flow requirements. No cover type is standard, making it suitable for applications where spatter resistance is not required—ideal for use in systems where only flow regulation is needed.
The Throttle (Needle) Valve Brass integrates directly into piping systems via its threaded connections and is compatible with both air and water media under specified conditions. The seal material uses HNBR rubber, offering improved ozone resistance; an FKM option is available upon request for specialized environments.
