Festo
558234
Soft-start valve VABF-S6-1-P5A4-N12-4-1-N
The Festo 558234 is a piloted piston gate valve based on the ISO 5599-2 norm, featuring electrical actuation with a soft sealing principle and internal pilot air supply. This component operates within a pressure range of 0.2 MPa to 1.2 MPa (2 bar to 12 bar) utilizing a pressurization valve function with a normally open contact, negative overlap, and mechanical spring reset. It incorporates both detenting and self-resetting manual overrides via electrical control signal, along with switching position sensing via sensor, supporting a max positive test pulse with 0 signal of 2500 µs and a max negative test pulse on 1 signal of 1400 µs. Built for any mounting position with vibration resistance to severity level 2 per FN 942017-4 and EN 60068-2-6 and shock resistance to severity level 2 per FN 942017-5 and EN 60068-2-27, it requires a forced dynamization switching frequency of at least once a month.

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.
