Festo
8038491
Soft start/quick exhaust valve MS6-SV-1/2-D-10V24P-2M12-SO-AG
The Festo 8038491 is a Size 6 industrial component from the MS series featuring a 62 mm width dimension, a piston seat structural design, and a soft sealing principle with a negative overlap. This electrically actuated, piloted 3/2-way closed monostable valve provides exhausting and pressurization functions with internal pilot air supply, mechanical spring reset, and piston magnet position sensing across an operating pressure range of 0.35 MPa to 1 MPa (3.5 bar to 10 bar). It achieves SIL 3 and category 3, performance level d for both exhausting and the prevention of unexpected start-up, conforming to DIN EN ISO 13849-1 and DIN EN ISO 13849-2 with a forced dynamization switching frequency requirement of at least once a month.

Request a QuoteWhy no listed price?
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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
