SRC/SMO O/O Double Seat Valve Service Kit in EPDM | Alfa Laval

The Alfa Laval SRC/SMO O/O Double-Seat Valve Service Kit in EPDM is the original maintenance kit with an O/O (O-ring over O-ring) sealing configuration for the double seat, designed for Alfa Laval i-SSV, SRC, SRC-LS, SMO, SMO-R, and SPC-1 series sanitary valves. Available in ISO 2.5" / DN 65 size—compatible with both ISO (2.5-inch) and metric (DN 65) connections—with high-quality EPDM elastomer (manufacturer's reference: 9611920031). The O/O configuration on the double seat provides a double sealing barrier on both valve seats, maximizing safety against cross-contamination between process and cleaning circuits. Manufacturer: Alfa Laval (Denmark).

Valve Compatibility

• Alfa Laval i-SSV — intelligent double-seat valve
• Alfa Laval SRC — standard double-seat valve
