Direct Acting Sequence Valve

A cross sequence valve is a type of hydraulic valve 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 valve 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 Sequencing 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 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 A Direct-Acting Sequence Valve Typically Works
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.
