High-Quality Proportional Valves | Visit Marginal Hydraulic

1. Proportional valve: Their use and application areas Industries like manufacturing and automotive require to maintain a precise control of fluid flow and pressure for the efficient operation of systems. This is where proportional valves come into play. These are sophisticated devices which are meant to offer fine-tuned control over hydraulic or pneumatic systems, making them essential components in many applications.

2. Understanding proportional valves Proportional valves are a type of electromechanical valve designed to control the flow rate or pressure of a fluid (liquid or gas) in direct proportion to an electrical input signal. Unlike traditional on/off valves, which function in a binary manner (either fully open or fully closed), proportional valves allow for variable positioning. This variable control enables precise adjustments of fluid flow or pressure, depending on the system's requirements. Working of proportional valves Proportional valves receive an electrical signal (voltage or current) from a controller. This signal activates a solenoid or electromagnetic coil within the valve. The coil moves a spool or diaphragm inside the valve, adjusting its position proportionally to the input signal. As the valve opens or closes incrementally, it regulates the flow rate or pressure of the fluid passing through it. The continuous feedback and precise control provided by proportional valves make them ideal for dynamic systems that require constant adjustments. Uses of proportional valves Proportional valves are required for a wide range of industries and applications due to their versatility and precision. Industrial automation Here, these valves are used in CNC machines to regulate the hydraulic or pneumatic pressure for accurate machining processes. In robotics,

3. it is used for controlling fluid flow in robotic arms to ensure smooth, precise movement. Automotive industry These valves are used in brake systems to manage hydraulic pressure in advanced braking systems for smooth and safe stopping. They are also useful for transmission control for adjusting hydraulic pressure to shift gears smoothly in automatic transmissions. Medical equipment In this industry, proportional valves are used in ventilators for regulating airflow and pressure to ensure precise oxygen delivery to patients. Dialysis machines also feature these valves for controlling the flow rate of blood and dialysis fluid for effective treatment. Aerospace Flight control systems feature proportional valves to manage hydraulic pressure for the precise movement of control surfaces like ailerons and rudders. They are also used in fuel system. Food and beverage industry Used to control the flow rate of liquids to ensure accurate filling of bottles or containers.
