Festo
8191406
Proportional pressure control valve VEAB-L-26-D9-Q4-LK-1R1
The Festo 8191406 is an 18 mm wide industrial component featuring a 3-way proportional pressure control valve closed design with non-reversible flow direction and direct electrical control using a mechanical spring reset. This unit operates with an inlet pressure range of 0 MPa to 0.65 MPa, accommodates an ambient and medium temperature range of 5 °C to 50 °C, and incorporates QS-4 pneumatic connections for ports 1, 2, and 3 along with EPDM, HNBR, and NBR sealing materials. Measuring 18 mm x 60.5 mm x 85 mm, it supports any mounting position via through-hole, alternative, or accessory configurations while maintaining a total leakage of 1 l/h within a 5 to 85% relative air humidity range.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
