What is the primary function of a sequence valve in a pneumatic system?

The primary function of a sequence valve in a pneumatic system is to manage the operation of multiple actuators in a specific order or sequence. This is crucial in applications where certain tasks must be completed before others can begin, ensuring that components of a system work together harmoniously and efficiently. For example, in a system where one actuator must extend before another can retract, the sequence valve controls the timing and sequence of these actions, providing the necessary coordination.

By routing airflow appropriately to pneumatic devices, the sequence valve ensures that output from one actuator prompts the next operation in a predetermined order. This capability is particularly important in complex processes, such as automated assembly lines or molding applications, where precise timing enhances productivity and prevents malfunction or damage to machinery.

In contrast, controlling air pressure levels, adjusting actuator speed, and filtering air supply are duties associated with different components or systems within pneumatic technology. Each of these functions plays its role, but the unique purpose of the sequence valve lies in orchestrating multiple actuators to work in a defined sequence, which is essential for the smooth functioning of automated pneumatic systems.
