Festo
8198578
Solenoid valve VSVA-B-T22C-MZH-D1-F8
This Festo 8198578 industrial component features a 2x2/2 closed, monostable valve function with an electrical actuation type and a piloted control using an external pilot air supply port. Built with a piston gate valve structural design, a soft sealing principle, and a positive overlap lap, the unit delivers a standardized nominal flow rate of 1700 l/min across an operating pressure range of -0.09 MPa to 1 MPa. The assembly includes a mechanical spring reset method, a non-detenting manual override, an adjustable exhaust air function via an individual sub-base, and an ISO 5599-1 size 1 pneumatic working port compliant with ISO 5599-1 standards. Featuring an IP65 and NEMA 4 degree of protection, a nominal width of 8 mm, and a reversible flow direction, it accommodates any mounting position within its 42 mm width dimension.

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.
