Proportional valves
As a driver of innovations in pneumatics with extensive expertise in proportional technology, Festo offers a wide range of proportional valves: proportional-pressure regulators and proportional directional control valves. This will allow you to implement even the most complex of applications easily and reliably. At Festo, you benefit from a huge number of individual solutions and functions that only require minimum effort to mount, parameterise and commission. All proportional valves are generally preset at the factory, while integrated technologies allow you to save time on laborious routine tasks.

Proportional flow control valves control the flow for connected pneumatic consumers. In this section, you will also find proportional directional control valves, piezo valves and valve units as well as proportional flow control valves. Find out about the benefits of each Festo valve.
Proportional flow control valve VEMD
Proportional flow control valve VEMD is ideal for mass flow control and is characterised by compact installation dimensions. Its truly lightweight design makes it ideal for use in mobile devices for controlling the flow rate. The valve operates precisely and dynamically thanks to the integrated control loop with thermal sensor. It reacts very quickly to a setpoint change and is almost immediately ready for operation.
