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.

You have a choice of various valve series with different working pressures, nominal widths, flow rate ranges and working temperatures, so you can always find the optimal proportional valve for your needs at Festo. We can adapt the valves completely to your individual wishes and special requirements.
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 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.
Short response time, high repeat accuracy, compact size, free of PWIS and certification for ATEX 3GD are all features that make proportional flow control valve VPCF unique. It is perfect for demanding applications, such as controlling inert gas, air flow rates and speed in painting and continuous flow systems; it also meets stringent requirements for dynamic response, repeat accuracy and linearity of the characteristic curve.
The proportional directional control valve MPYE is a 5/3-way proportional valve and has a position-controlled spool. This converts an analogue input signal into a corresponding opening cross-section at the valve outputs. When combined with an external position controller and displacement encoder, this can be used to create a precise pneumatic positioning system.
When combined with a sensor, the piezo valve VEMP can be used as a control valve. This small and lightweight valve is used for proportional control of pressure or flow rates and is suitable for use in mobile devices such as in medical technology.
The piezo valve VEAE is energy-efficient, lightweight and quiet. It is suitable wherever flow rates of up to 80 l/min need to be controlled precisely and reliably, for instance in stationary or mobile applications in medical technology.
The pilot-operated pressure regulator with selectable pressure regulation range is optionally available with a setpoint module. The setpoint is entered as an analogue voltage or current signal and the electrical connection is made via a plug.
