Abstract: We compute exact vacuum expectation values of physically relevant scaling fields in the perturbed $Z_N$ parafermionic models. Our algebraic method is based on analyzing vertex operators in the corresponding off-critical lattice model. The results coincide with the expressions derived by perturbed conformal field theory methods.

Keywords: integrable model, conformal field theory, vacuum expectation value, parafermionic symmetry, vertex operator.
