Festo
The Festo Size 6 industrial component from the MS series is a 3/2-way closed monostable valve featuring a piston seat structural design with negative overlap, soft sealing principle, and internal pilot air supply port. Operating at a pressure range of 0.35 MPa to 1 MPa (3.5 bar to 10 bar), it provides electrical actuation, mechanical spring reset, and a piston magnet position sensing principle with non-throttleable exhaust air function. Conforming to DIN EN ISO 13849-1 and DIN EN ISO 13849-2 standards, this unit achieves SIL 3 and Category 3 Performance Level d for both exhausting and the prevention of unexpected start-up (pressurization), requiring a forced dynamization switching frequency of at least once a month.
