Direct Acting Sequence Valve
A direct acting sequence valve is a hydraulic pressure control valve type used to control the sequence of operations in a hydraulic system. It is designed to allow the flow of hydraulic fluid to a secondary circuit or actuator only when a predetermined pressure is reached in the primary circuit. Direct-acting sequence valves are commonly used in hydraulic systems where specific operations need to occur in a predetermined sequence. They ensure that certain actions or functions take place only when the required pressure is reached, providing reliable and efficient control over the system’s operation.
What Is A Direct Acting Sequence Valve?
A sequencing valve, specifically a direct-acting sequence valve, is a type of hydraulic valve used to control the sequential operation of hydraulic actuators or cylinders in a hydraulic system. It ensures that specific actions occur in a predetermined order by controlling the flow of hydraulic fluid to the actuators.
Direct-acting sequence valves are widely used in valve applications where precise sequencing of hydraulic actuators is required. They are commonly found in machinery, manufacturing equipment, and systems that involve complex movements and coordinated operations.

How Is Sequence Valve Working
Valve Structure
A direct-acting sequence valve consists of a valve body, a valve spool or poppet, and various ports for hydraulic fluid flow. The valve is typically spring-loaded.
01
Inlet and Outlet Ports
The valve has an inlet port that receives pressurized hydraulic fluid from a pump or another power source. It also has one or more outlet ports that are connected to the hydraulic actuators or cylinders.
02
Set Pressure
The valve is designed to open and allow fluid flow to the outlet ports once the pressure at the inlet port exceeds a specific pre-set pressure level. This pressure level is often adjustable and determines the sequencing order.
03
Pressure Differential
When the pressure at the inlet port surpasses the set pressure, it acts on the valve spool or poppet, overcoming the spring force and initiating valve movement.
04
Flow Diversion
As the valve opens, hydraulic fluid is allowed to flow to the outlet ports. This enables the actuator or cylinder connected to the first outlet port to begin its intended operation.
05
Sequential Operation
Once the actuator connected to the first outlet port completes its stroke or reaches its end position, the pressure at the outlet port decreases.
06
Valve Reset
As the pressure drops at the first outlet port, the spring force becomes stronger than the pressure force, causing the valve to close and redirect the hydraulic fluid flow to the subsequent outlet port.
07
Subsequent Actuators
The hydraulic fluid flow is then directed to the next outlet port, activating the second actuator in the predetermined sequence. This process continues until all the desired actuators have completed their strokes.
Direct Acting Sequence Valve Applications
Machine Tooling
In manufacturing processes, such as machining or assembly lines, direct-acting sequence valves can be used to control the movements of different tools or workpieces. They ensure that specific actions occur in the correct order to achieve efficient and accurate production processes.
Material Handling Equipment
For equipment like conveyor systems, robotic arms, or lifting platforms, cross sequence valves can control the movements of various components. This helps in moving materials or products through different stages of the process with proper synchronization.
Automated Packaging
In packaging machinery, direct acting sequence valves can control the movements of packaging materials, ensuring that items are filled, sealed, labeled, and moved in the correct order. This is essential for maintaining consistent product quality and reducing errors.
Presses and Punches
In metalworking applications, direct-acting sequence valves can be used to control the movements of presses and punches. This ensures that the material is positioned accurately before the pressing or punching operation occurs, minimizing waste and improving precision.
Construction Machinery
Direct-acting sequence valves can be used in construction equipment like hydraulic cranes or excavators. They help coordinate movements to ensure safe and efficient lifting, digging, or other actions.
Aircraft Landing Gear Systems
In aviation, direct-acting sequence valves can be employed to control the order in which landing gear components extend or retract during takeoff and landing. This ensures that the landing gear operates smoothly and safely.
