The Speed Controller Brass is a precision flow control device designed to regulate air flow speed in industrial pneumatic systems. Its primary function is to provide accurate and consistent adjustment of airflow by enabling linear control via a dial mechanism, allowing operators to set and monitor speed directly using an integrated indicator.
The main resin components are manufactured from PBT (polybutylene terephthalate), a standard engineering plastic suitable for general environmental conditions. The primary metal parts are constructed from brass with electroless nickel plating, which enhances corrosion resistance and ensures long-term durability in typical industrial settings.
The device features a dial interface with scales marked on both the upper and lower sides of the body, allowing users to visually confirm speed settings. Speed is directly proportional to knob rotation, enabling intuitive and precise adjustments. The indicator allows for real-time verification of the current speed setting during operation.
The Speed Controller Brass operates within an air flow medium, with a pressure range from 0.1 to 1.0 MPa. It has a check valve cracking pressure of 0.05 MPa and is rated for operating temperatures between 0°C and 60°C (no freezing). Flow rate increases linearly with knob turns, ensuring predictable performance across the entire speed range.
Available in multiple sizes, the product offers metric diameters of φ3, φ4, φ6, φ8, φ10, and φ12 mm, equivalent to inch sizes of φ1/8, φ5/32, φ3/16, φ1/4, φ5/16, φ3/8, and φ1/2. Thread options include metric male threads (M3x0.5, M5x0.8), taper pipe male threads (R1/8, R1/4, R3/8, R1/2), and standard UNF (10-32UNF) and NPT (NPT1/8, NPT1/4, NPT3/8, NPT1/2) connections.
The Speed Controller Brass is designed for direct integration into pneumatic systems via its threaded interfaces. It supports installation using metric male threads, taper pipe threads, or standard UNF and NPT threads, making it compatible with a wide range of industrial piping and control configurations.
