Festo
558231
Soft-start valve VABF-S6-1-P5A4-N12-4-1
The Festo part number 558231 is an electrically actuated piston gate valve featuring a soft sealing principle, piloted control with internal pilot air supply, and a mechanical spring reset method. Designed based on the ISO 5599-2 norm with any mounting position, it provides an operating pressure range of 0.2 MPa to 1.2 MPa (2 bar to 12 bar), a switchover pressure presetting of 0.4 MPa, a standard nominal flow rate pressurization of 3000 l/min, and a standard nominal flow rate exhaust air of 3300 l/min. This component accommodates a maximum positive test pulse with a 0 signal of 2500 µs, a maximum negative test pulse on a 1 signal of 1400 µs, and features both detenting and self-resetting manual override via an electrical control signal.
