What type of pressure is present at the outlet of a sequence valve?

The pressure present at the outlet of a sequence valve is line pressure. Sequence valves are designed to control the operation of hydraulic circuits by allowing fluid to flow through them in a specific sequence. When pressure reaches a certain threshold in the circuit, the sequence valve opens, allowing fluid to pass from the inlet port to the outlet port.

Line pressure refers to the pressure that is maintained in the hydraulic system while fluid is being actively delivered to the components. In this context, as the sequence valve opens, it permits the line pressure present upstream to flow through to the outlet side, ensuring that the downstream components receive the required hydraulic pressure for operation.

Understanding this concept is essential in hydraulics, as maintaining sufficient line pressure is crucial for the effective functioning of hydraulic machinery and devices. The sequence valve, by managing the flow based on specific pressure conditions, plays a critical role in ensuring that components only receive fluid when it is safe and appropriate for them to operate.
