Air solenoid valve VSNC-FC-M52-MD-N14-FN-1A1-EX4-A

The Festo 577286 is a 32 mm wide electrical piston gate valve featuring a switchable 5/2- or 3/2-way valve function and a NAMUR pneumatic working port connection pattern. It delivers a normal nominal flow rate of 1250 l/min at an operating pressure range of 0.25 MPa to 0.8 MPa (2.5 bar to 8 bar) utilizing 24V DC operating voltage, mechanical spring reset, adjustable exhaust air function, and a soft sealing principle in any mounting position. Certified with IP65 protection via plug socket per IEC 60529, it holds ATEX category II 2G and II 2D ratings, IEC-EX EPL Ga and Db certifications, and DNVGL-TAA000011J approval, supporting Ex ia IIC T6 Ga gas and Ex t IIIC T80°C Db dust ignition protection across an explosive ambient temperature range of -40°C to +50°C.

Why 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.
