I've a use case where I need to store values for eg. SADD key *values

but I also want to persist the values only for certain duration say 1 day after which the specific value should get expired.

Please suggest how can this be achieved using redis.

Redis' expiration is implemented at key level, not inside the value. As an alternative, use a Sorted Set, with the score of each member being its expiration timestamp.

You will have to "expire" elements manually, so periodically call ZREMRANGEBYSCORE to remove all elements with a timestamp lower than now.
