Pilot Operated Directional Control Valve

Pilot-operated valves use a smaller pilot valve to control a larger main valve. This arrangement allows for the application of lower control forces, making it easier to operate the valve manually or with smaller control mechanisms. The pilot valve serves as a control element that initiates the movement of the main valve, reducing the force required for operation.

Pilot-operated valves offer precise control over the movement and positioning of the main valve. By utilizing a pilot valve, the system can achieve fine adjustments and proportional control of the fluid flow or pressure, resulting in accurate control over the hydraulic system's operation.

Pilot-operated valves can handle high flow rates and pressures while maintaining precise control. The use of a smaller pilot valve to control a larger main valve allows for the efficient management of fluid flow, ensuring optimal performance even in systems with high flow demands.

The pilot valve's smaller size and reduced contact area result in lower friction compared to directly operated valves. This helps in reducing wear and tear, improving the overall longevity and reliability of the valve.

Pilot-operated valves offer the advantage of remote operation. The pilot valve can be located at a different position, allowing for control and actuation of the main valve from a remote location. This is particularly useful in systems where the valve needs to be operated in a separate control room or from a central control panel.
