Festo
The Festo 8191409 is a directly actuated 3-way proportional pressure control valve closed featuring a non-reversible flow direction and a mechanical spring reset method. Measuring 18 mm x 67 mm x 66 mm with an 18 mm width dimension, this component utilizes a soft sealing principle with EPDM and HNBR seals, flange connections for ports 1, 2, and 3, and supports an inlet pressure of 0 MPa to 0.2 MPa. It operates within an ambient and medium temperature range of 0 °C to 50 °C and 5 °C to 50 °C respectively, maintains a total leakage of 1 l/h, and offers versatile mounting via through-hole, accessories, or alternative positions.
