A sequence valve is a type of pressure control valve that ensures actuators, such as hydraulic cylinders, operate in a specific sequence within hydraulic circuits. This is crucial for systems requiring a predetermined order of operations, allowing for one actuator to complete its task before the next begins.
Sequence valves are integral to various industries and machinery, including food and semiconductor manufacturing, as well as construction equipment like cranes and forklifts. These valves enable the precise control of power in hydraulic systems, facilitating the movement of machine tools and large machinery.
In press machines, sequence valves control the sequential operations from material input to product discharge, ensuring large forces are applied in a controlled manner.
Used in mobile cranes, sequence valves manage the order in which the crane's jibs extend and retract, ensuring smooth operation.
A sequence valve directs flow from the primary side to the secondary side once the primary pressure exceeds a set threshold. This action is controlled by a spool within the valve that moves in response to pressure changes, allowing sequential actuator operation.
Comprising a body, spool, ports, a pressure adjustment screw, a spring, and a check valve, sequence valves feature input, output, and drain ports. The operation timing can be finely adjusted via a spring under the adjusting screw.
Based on the source of pilot pressure, sequence valves are categorized into:
Selection criteria include the pressure and flow rate of the circuit, which influence the timing and force of operations. Proper selection is crucial to prevent damage and ensure efficient operation. Understanding the override characteristic, where output gradually shifts to the secondary side before reaching the set pressure, is also important.
The typical operating sequence in a hydraulic circuit involves:
This process ensures that each actuator operates in turn, based on the preset pressure thresholds.
