Festo
8191408
Proportional pressure control valve VEAB-L-26-D12-Q4-LK-1R1
The Festo 8191408 is a 3-way proportional pressure control valve closed featuring direct electrical actuation and a mechanical spring reset method in a non-reversible flow configuration. Measuring 18 mm x 60.5 mm x 85 mm with an 18 mm width dimension, this component incorporates a soft sealing principle utilizing EPDM, HNBR, and NBR seals and operates with QS-4 pneumatic connections for ports 1, 2, and 3. It accommodates an inlet pressure range of 0 MPa to 0.1 MPa, an ambient temperature range of 0 °C to 50 °C, a medium temperature range of 5 °C to 50 °C, and an overall leakage rate of 1 l/h while supporting any mounting position via through-hole, alternative, or accessory configurations.
