If a pneumatic cylinder moves too fast, loses precision or generates impacts, the problem is probably not with the cylinder.
In many pneumatic installations, true motion control depends on a small, economical and often undervalued component: the throttle and non-return valve.
Choosing this element correctly allows you to:
In this article we explain what a throttle and non-return valve does, when to use it and why the Festo VFOE has become a very interesting solution for standard industrial applications.
It is a pneumatic component designed to regulate air flow in one direction and allow free passage in the opposite direction.
Its main function is to control the displacement speed of a pneumatic actuator without affecting air return.
In other words:
This principle allows much smoother and more controlled movements to be achieved.
A throttle and non-return valve is used when you need to control:
It is one of the most widely used elements in:
When air flows in the opposite direction, a non-return valve opens and allows virtually free passage.
This design offers precise motion control without penalizing system performance
This is one of the most common questions among maintenance managers.
Correctly regulating speed allows you to:
In many cases a small adjustment prevents breakdowns that generate hours of downtime.
Among current pneumatic solutions, the Festo VFOE series is designed for standard applications where rapid installation, low cost and reliability are sought.
Their characteristics include:
Very compact design
It takes up very little space and can be installed directly on the actuator.
Ideal for machinery with limited available space.
Quick and secure adjustment
It incorporates the Push-to-Lock system, which allows flow regulation and locks the adjustment to prevent accidental modifications during operation.
Easy identification
The inlet and exhaust throttle versions are differentiated by colors, facilitating assembly and reducing installation errors.
Lower weight
Thanks to the use of polymeric materials it can be up to 50% lighter than previous generations of similar valves.
Wide variety of connections
Available in multiple thread sizes and quick connections to adapt to different pneumatic installations.
At ROYSE we usually recommend this solution for:
Its compact size particularly facilitates assembly when available space is limited.
At ROYSE we work with leading manufacturers such as Festo to offer automation solutions adapted to each project.
We do not only supply pneumatic components; we help select the most efficient solution according to the application, optimizing performance, reliability and maintenance cost.
If you are designing a new machine or want to improve an existing installation, our technical team can advise you to choose the most suitable valve.
A regulating valve maintains a specific pressure.
A throttle valve regulates air flow to control actuator speed.
It depends on the application.
In most industrial pneumatic installations it is recommended to control the exhaust to achieve more stable movement, although there are applications where it is preferable to regulate the supply. The VFOE has versions for both configurations.
Yes.
Precisely one of the strong points of the VFOE series is its extremely compact and lightweight design.
