Let E : 0 → A

f→ B

g→ C → 0 be a short exact sequence of modules and module homomorphism. E is called gd-closed sequence if Im f is gd-closed

in B. In this paper, the proper class GD − Closed, which is coprojectively generated by modules with projective socle, be studied and also its relations among

N eat, Closed, D − Closed, S − Closed be investigated. Additionally, we examine coprojective modules of this class
