A sequence valve is primarily used for?

A sequence valve is primarily used to control the timing of two cylinders in a hydraulic circuit. This valve functions by allowing fluid to flow through it only when a predetermined pressure is reached in one part of the system, effectively coordinating the operation of multiple cylinders by managing their sequence.

In scenarios where timing and synchronization of hydraulic components are crucial, such as in pressing or assembly operations, sequence valves ensure that one action occurs only after another has been completed. This helps in preventing potential mechanical issues that could arise from overlapping operations or uncontrolled movements.

While a sequence valve can influence aspects of pressure and load balancing, its primary function revolves around establishing the correct operational sequence for hydraulic actuators. Therefore, the focus on timing makes it clear why this answer is appropriate.
