Direct-Acting vs Pilot-Operated Valves Key Differences
There are two types of pneumatic valves which are pilot and direct-acting valves used in hydraulic and pneumatic systems. Direct-acting valves are only used for low-flow applications as they are operated through mechanical force which makes them faster. On the other hand, pilot-operated valves use system pressure which helps them in valve movement to handle higher pressures and flow rates easily. As pilot-operated valves are energy-efficient and better for high-load applications, direct-acting valves are suitable for quick responses. The selection depends on system requirements pressure and flow capacity. Understanding Direct-Acting and Pilot-Operated Valves What is a Direct Acting Valve? A direct-acting valve is one that can differentiate itself from others because it operates without any additional pressure assistance. When the solenoid is activated, the valve is either opened or closed. This operating principle makes direct-acting valves exceptional in low-pressure sys...
