Festo
The Festo 8153673 is a 3-way proportional pressure control valve featuring direct electrical actuation and a mechanical spring reset method within a soft-sealing configuration. Measuring 18 mm x 60.5 mm x 85 mm with NBR seals, this component utilizes QS-4 pneumatic connections for ports 1, 2, and 3 while supporting an inlet pressure range of 0 bar to 1 bar and an output pressure range of 0.1 kPa to 20 kPa. It operates within an ambient temperature range of 0 °C to 50 °C, handles medium temperatures from 5 °C to 50 °C, maintains a total leakage of 1 l/h, and permits mounting in any position via through-hole or designated accessories.
