Festo
8161611
Soft-start valve VABF-S6-1-P5A4S1S-G12-1T1L-PZ
This Festo industrial component, part number 8161611, is a 40 mm piston gate valve featuring an electrical actuation type, piloted control with an internal pilot air supply port, and a soft sealing principle. Designed with a non-reversible flow direction, negative overlap lap, mechanical spring reset method, and NC contact switching element function, it provides pressurization and exhaust valve functions with no manual override and an any mounting position. The assembly withstands transport application vibration per FN 942017-4 and EN 60068-2-6 severity level 2, and shock per FN 942017-5 and EN 60068-2-27 severity level 2, while accommodating a maximum positive test pulse with a 0 signal of 2000 µs and a maximum negative test pulse on a 1 signal of 1200 µs.
