Festo
577257
Air solenoid valve VSNC-FC-M52-MD-G14-F8
The Festo 577257 is a piloted piston gate valve featuring a switchable 5/2- or 3/2-way valve function with a 32 mm width and a NAMUR pneumatic working port connection pattern conforming to VDI/VDE 3845 standards. It delivers a normal nominal flow rate of 1250 l/min using internal pilot air supply, an operating pressure range of 0.25 MPa to 1 MPa, adjustable exhaust air, and mechanical spring reset with both detenting and non-detenting manual override. This unit includes soft sealing, positive overlap, non-reversible flow direction, and any mounting position while operating via a solenoid coil ordered separately and carrying c UL us recognition and DNVGL-TAA000011J certification.

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.
