B737 Bleed press. differentials

Hi ,
Can anybody tell me (technically speaking) about the maximum allowable differential L and R needle of bleed pressure ? On my recent flight with 735 the L -49 psi & R-12 psi on CLB thrust, and L-46 & R-28 on CRZ thrust, on DES relatively equals at 26 psi. No light illuminates, and pressurization is normal.
Thanks.
