The APR series of regulators are designed to control air pressure down to 1/100 psi, or a few mm of water gauge, on sensitive production processes.  When connected directly to the factory air supply via a flow control valve the regulator balances the output pressure against the tension of a low rate spring and expels surplus air to atmosphere. With the relief valve hung vertically on the balance spring and literally floating on a cushion of air, friction is negligible.  This produces a Hysteresis free output pressure as either input pressure or output flow changes.  An oil chamber below the air relief valve adds viscostatic damping and ensures short-term stability
