Function:

Crane upper manoeuvring valve is an important part of the hydraulic system, the main role is as follows:
1. control the flow of hydraulic oil: crane upper manipulation valve is a kind of directional control valve, through the handle operation, can be high-pressure hydraulic oil distribution to different hydraulic actuating elements (such as hydraulic cylinders, hydraulic motors, etc.), so as to achieve a variety of crane action. 2. to achieve a variety of functional operations: the manipulation valve can control the hoisting, slewing, telescoping and other mechanisms.
2. Realise a variety of functional operations: the manipulating valve can control the crane's lifting, luffing, slewing, telescoping and other institutional actions. For example, the manoeuvring valve can control the telescoping of the boom, the lifting and lowering of the hook and the rotation of the crane.
3. Micro-motion and load-sensitive control: Modern crane upper manipulating valve usually adopts load-sensitive technology, which can automatically adjust the flow and pressure of hydraulic oil according to the change of load, so as to realise precise micro-motion control and improve the flexibility and safety of operation.
4. Protect the hydraulic system: the manoeuvring valve also has certain protection functions, for example, by restricting the flow and pressure, preventing the hydraulic system from overloading and protecting the hydraulic components from damage.
5. energy saving and consumption reduction: some advanced manoeuvring valves using energy-saving design, such as spool stroke limitation and flow distribution system, can be in the flow is insufficient to proportionally reduce the speed of each actuator, to avoid energy waste.
