- Control Proportional Valve
In summary, a 5/3-way proportional directional control valve VPWP operates by using solenoids to control the movement of a spool, allowing for proportional flow of fluid. It typically has 5 ports, including Pump and Tank ports, DCV extend and retract ports, and a fifth port for signaling, braking, or interlocking. The valve has three states and is commonly used in electrically controlled, hydraulically operated servo systems. The Festo VPWP is an integrated pneumatic product with control solenoids, LED indicators, and pressure sensors. For more information on how it works and its application, please refer to the provided links.

Welcome to PF.
It will depend on who makes it. 5/3 suggests 5 ports, with three states, with proportional flow decided by solenoid current. Maybe for use in an electrically controlled, hydraulically operated, servo system.
Do you understand how normal Directional Control spool Valves operate ?
https://en.wikipedia.org/wiki/Directional_control_valve
It would probably be a proportional cross-over spool valve with a solenoid at each end, spring loaded to rest in the centre = neutral position. Each solenoid would move the spool in a different direction. As solenoid current is increased the valve moves further and allows more fluid to flow through the valve. The 5 ports suggests it has the normal Pump and Tank ports, P&T, plus the DCV extend and retract ports, A&B. The fifth may be a signalling, brake or interlock line.
Can you please give a link to the particular hydraulic valve you are referring to, and explain your intended application.

When in neutral middle position all paths are blocked.
The ports 1, 2, 3, 4, & 5 are connected differently in the two end positions.
Imagine sliding the middle of the diagram sideways.
These are the three connection states.

The device you show in post #3 is not a simple DCV. It is an integrated pneumatic product manufactured by Festo. It includes control solenoids, LED indicators and pressure sensors. The full data sheet is here;

1. What is a 5/3-way proportional directional control valve VPWP?
A 5/3-way proportional directional control valve VPWP is a type of valve used in fluid power systems to control the direction and flow of fluid. It has five ports and three positions, allowing for precise control over the flow of fluid.
2. How does a 5/3-way proportional directional control valve VPWP work?
The valve has a spool inside that can move between three positions, controlling the flow of fluid through the five ports. It uses proportional solenoids to control the movement of the spool, allowing for precise and proportional control of the fluid flow.
3. What are the advantages of using a 5/3-way proportional directional control valve VPWP?
One advantage is the ability to control the flow of fluid with precision and accuracy. This can be especially useful in applications where precise control is necessary, such as in industrial machinery. Additionally, the proportional control allows for smooth and gradual changes in the fluid flow, reducing the risk of damage to the system.
4. What are the common applications of a 5/3-way proportional directional control valve VPWP?
This type of valve is commonly used in hydraulic and pneumatic systems, such as in industrial machinery, automation equipment, and mobile equipment. It can also be found in applications where precise control over fluid flow is necessary, such as in medical equipment and laboratory instruments.
5. How do I select the right 5/3-way proportional directional control valve VPWP for my application?
When selecting a valve, consider factors such as the required flow rate, pressure, and fluid type. You should also consider the voltage and current requirements for the proportional solenoids. It is recommended to consult with a fluid power expert or refer to the manufacturer's specifications for guidance in selecting the right valve for your specific application.
