The AIRMIXS STU-G3/4 is a heavy-duty, bidirectional flow control (throttle) valve designed for high-flow pneumatic or hydraulic applications. Engineered from high-grade stainless steel, this valve provides exceptional resistance to corrosion and chemical exposure, making it a premier choice for marine, food processing, and pharmaceutical environments.

The STU series features a precision-machined internal needle controlled by a knurled adjustment knob with a laser-etched graduated scale. This allows operators to achieve highly repeatable flow settings to synchronize actuator speeds across industrial systems. Its robust, inline hexagonal body is designed to handle significant mechanical stress and high operational pressures without deformation.
