  We predict angle-dependent superfluidity for a new class of 2D materials --
transition metals trichalcogenides (TMTC). Within a mean-field approach
superfluidity of indirect excitons in TMTC van der Waals heterostructures
(vdWHs) is studied. We use different potentials for charged carriers
interaction to analyze the influence of the screening on the studied phenomena.
Our study demonstrates the angle-dependent superfluidity temperature in TMTC
vdWHs: for a given density a maximum and minimum $T_c$ of superfluidity occurs
along chain and $a$-directions, respectively. This work can guide experimental
research toward the realization of anisotropic superfluidity in TMTC vdWH. We
suggest an experiment for the observation of anisotropic superfluidity in TMTC
vdWH.
