The in-line speed controller consists of a stainless steel body with a adjustable throttle mechanism. It is designed for inline installation, meaning it is mounted directly in the air line. The valve allows precise adjustment of air flow, with a typical adjustment range of 10 (8) turns. It is suitable for use with air as the medium, operating within a working pressure range of 0.095 to 1.6 MPa, a proof pressure of 1.6 MPa, and a vacuum capability of -100 KPa (10 Torr). The temperature range is 5 to 100 °C. Typical construction includes a stainless steel body, internal seals, and a adjustment knob. It is used to control the speed of pneumatic actuators, cylinders, and other air-driven devices. When requesting a quote, specify: tube size (4, 6, 8, 10, or 12 mm), thread size (M5x0.8p, 1/8, 1/4, 3/8, or 1/2), body material (stainless steel), adjustment turns (10 or 8), quantity, and packaging requirements. Additional parameters such as seal material and flow rate may be required; provide these if critical to your application.
