👉 A control fluid, often used in hydraulic systems, is a specialized liquid or gel that serves as the medium for transmitting force and controlling motion. Unlike regular hydraulic fluids, control fluids are designed to maintain consistent viscosity under varying temperatures and pressures, ensuring reliable performance. They are integral in systems like brakes, steering mechanisms, and power steering, where precise control over movement is essential. By adjusting the fluid's flow rate through valves, operators can modulate the force applied to components, allowing for smooth and responsive control. This fluid's unique properties make it indispensable in applications requiring high precision and reliability, such as automotive and aerospace engineering.
