Festo
4514999
Pneumatic valve VOFD-L50T-M32-MN-FG14-10-F10
The Festo 4514999 is a 3/2-way closed, monostable directly actuated poppet valve with a 50.5 mm width, a 5 mm nominal width, and a normal nominal flow rate of 493 l/min normalized to DIN 1343. This electrical component features a soft sealing principle, a mechanical spring reset method, a reversible flow direction, and a pneumatic working port with a flange 1/4 NAMUR connection pattern supporting an operating pressure range of 0 MPa to 1 MPa, 0 bar to 10 bar, and 0 psi to 145 psi. Certified by TÜV 968/V 1251.02/24, it provides an IP65 degree of protection, vacuum suitability, a b-value of 0.25, safe exhausting safety function, and suitability for up to SIL 3 high and low demand mode operations in any mounting position without manual override.

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.
