Many colleges provide PGDM course with AICTE approval but not with AIU. Is degree from these colleges valuable as MBA?

Yes it is very important. Do a detailed research about the college u want to join in and the Approvals it has if it is offering PGDM it should be AICTE approved and AIU approved and if it is offering MVA it should be approved by UGC

Yes it is as Valuable.
