Sequence Valves

Sequence Valves: Precision Control, Seamless Performance!

A sequence valve is a type of hydraulic valve used in fluid power systems to control the sequence in which different parts of a hydraulic circuit are activated. Essentially, it ensures that certain operations or actions are performed in a specific order.

Example:

In a manufacturing system with two cylinders, you might want the first cylinder to extend fully before the second cylinder begins its motion. A sequence valve can be used to ensure that the first cylinder is fully extended (i.e., pressure reaches a certain level) before the second cylinder is allowed to operate.

Overall, sequence valves are important for ensuring that hydraulic systems operate in a controlled, sequential manner, improving efficiency and preventing damage to equipment.

How does it work?

• Setting the Pressure: A sequence valve is typically set to open and allow fluid flow only once a certain pressure threshold is reached. This ensures that the first operation is completed before the next one begins.
• Controlling Multiple Actuators: In systems with multiple actuators (such as cylinders or motors), the sequence valve can control the timing and order of actuation, ensuring the proper sequence of operations, such as in a manufacturing process or in a hydraulic lifting system.
• Backflow Prevention: Sequence valves are usually one-way valves that prevent backflow of the fluid, ensuring that the fluid only flows in one direction and the system remains in the correct sequence.

Common applications:

• Hydraulic Presses: Ensures cylinders operate in the correct order.
• Lifting Systems: Manages the sequence of hydraulic cylinders in cranes and lifts.
• Conveyor Systems: Synchronizes the operation of multiple actuators.
• Injection Moulding: Controls the sequence of actions in moulding machines.
• Machine Tools: Manages tool changers and other components in CNC machines.
• Aviation: Controls landing gear and flight surface operations.
• Construction Equipment: Synchronizes hydraulic functions in excavators and bulldozers.
• Manufacturing Lines: Ensures smooth assembly processes in production lines.
• Oil & Gas: Controls drilling equipment and safety systems.
• Agricultural Machinery: Manages hydraulic operations in tractors and harvesters.
