Product Overview
The FESTO VEAB-L-26-D9-Q4-V1-1R1 is a precision proportional pressure regulator from Festo’s VEAB series, engineered for continuous, stepless control of output pressure in pneumatic and process automation systems. Operating on a direct-acting proportional valve principle, the unit modulates a poppet-type control element via an integrated solenoid actuator, delivering output pressure that is directly proportional to an analog electrical setpoint signal. With a nominal 26 mm size designation, the VEAB-L-26 platform is optimized for high flow capacity relative to its compact body, making it a preferred choice for closed-loop pressure regulation in dynamic industrial processes. The Q4 designation indicates a 4 mm push-in pneumatic connection, while the V1-1R1 configuration denotes a specific electrical interface and control variant within the VEAB family. This regulator serves as a critical control element in pressure-controlled circuits, offering fast response, excellent repeatability, and minimal hysteresis for demanding automation tasks.
