Introduction
Pilot operated switching valve is a key control element in a hydraulic system, which realizes precise control of hydraulic components by controlling the hydraulic pressure and flow in the hydraulic system. Pilot operated switching valve usually consists of valve body, spool, springs and seals, etc.
Its working principle can be divided into two stages: pressure balance stage and working stage.
Function
During the operating phase, when a hydraulic component in the hydraulic system needs to stop working or change its operating state, a control signal is sent to the pilot operated changeover valve. This control signal causes the spool to be displaced, changing the position of the spool and thus changing the hydraulic pressure and flow in the hydraulic system. The displacement of the spool is realized by controlling the pressure difference between the fluids on both sides of the spool. When the control signal causes the liquid pressure on one side of the spool to increase while the liquid pressure on the other side remains constant, the spool will move to the lower pressure side, changing the hydraulic pressure and flow in the hydraulic system.
The pressure and flow rate of hydraulic pressure in the hydraulic system will be changed.
In addition, the principle of operation of pilot operated switching valves involves the manipulation of pilot valves, which are auxiliary valves used to manipulate control mechanisms in other valves or components.
Application
Hydraulic proportional valves are offered as direct-operated or pilot-operated valves, with or without integrated electronics (OBE). Integrated electronics reduce cabling and simplify handling, making these valves ideal for many closed-loop applications.
