Festo
8198557
Solenoid valve VSVA-B-P53U-H-D1-F8
The Festo 8198557 is an electrical 5/3-way pressurized industrial component featuring a piston gate valve structural design with a soft sealing principle and positive overlap. Operating at pressures from 0.3 MPa to 1 MPa (3 bar to 10 bar), this 42 mm wide unit provides a standardized nominal flow rate of 1600 l/min through an ISO 5599-1 size 1 sub-base pneumatic working port. Incorporating a mechanical spring reset method, non-detenting manual override, internal pilot air supply port, and IP65 and NEMA 4 degree of protection, the assembly mounts in any position.

Request a QuoteWhy no listed price?
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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
