How Does A Hydraulic Selector Valve Work?

A hydraulic selector valve, also known as a hydraulic diverter valve or hydraulic control valve, is a device used to direct the flow of hydraulic fluid in a hydraulic system. It allows the operator to control the path of fluid flow by selecting different hydraulic circuits or components to operate. Here’s a breakdown of how a hydraulic selector valve works:

1. Valve Construction:
   • A hydraulic selector valve consists of a body with multiple ports and internal passages.
   • It typically has an actuating mechanism, such as a lever or a solenoid, to control the movement of the valve spool or poppet.
2. Port Configuration:
   • A selector valve has multiple ports, usually labeled as A, B, and C, or sometimes referred to as P, T, and A/B/C.
   • Port P (Pressure) connects to the hydraulic pump or the high-pressure side of the system.
   • Port T (Tank) connects to the hydraulic reservoir or the low-pressure side of the system.
   • Ports A, B, and C are the output ports that connect to different hydraulic circuits or components.
3. Valve Positions:
   • The selector valve has different positions that determine the flow path of the hydraulic fluid.
   • Common positions include “A,” “B,” “C,” “AB,” “AC,” and “BC,” depending on the specific valve design.
4. Fluid Flow Control:
   • When the valve is in the neutral or default position, typically labeled “N,” the fluid flow is blocked, and no flow occurs between any of the ports.
   • When the operator actuates the valve by moving the lever or energizing the solenoid, the valve spool or poppet shifts to a different position, enabling fluid flow.
5. Flow Path Selection:
   • By moving the actuating mechanism, the operator can select the desired flow path.
   • For example, when the valve is in position “A,” fluid flows from port P to port A, allowing the hydraulic circuit or component connected to port A to operate.
6. Multiple Flow Paths:
   • Depending on the specific valve design, a hydraulic selector valve can provide multiple flow paths.
   • For instance, in position “AB,” fluid can flow from port P to both ports A and B simultaneously, allowing operation of two separate hydraulic circuits or components.
7. Ohjaus ja toiminta:
   • The actuating mechanism of the selector valve can be manual, where the operator physically moves a lever or knob, or it can be electric or pneumatic, using solenoids or other control devices.
   • Electrically controlled selector valves can be integrated into automated systems or controlled remotely.
8. System Flexibility:
   • Hydraulic selector valves provide flexibility in system design and operation.
   • They allow the operator to switch between different hydraulic circuits or components, facilitating tasks such as equipment positioning, attachment control, or switching between different implements.
