Alfa Laval Unique SSV reverse acting lower change-over plug, ISO, complete with the standard EPDM plug seal fitted, DN 65 / 63.5 mm. 1.4404 (316L).
The lower plug of a reverse acting change-over valve, used where the direction of flow rules out a standard Unique SSV. Rated 10 bar and -10 °C to +140 °C on EPDM.
Unlike the bare plugs, this article is the complete assembly — Alfa Laval lists it as “complete, EPDM (standard)”, so no separate plug seal is needed.
