During operation, if is held against the orifice and there is no flow through inlet Pressure is lost, or decreases below the setpoint of the regulator. When demand increases, downstream the regulator, the downstream Pressure will back flow Pressure drops slightly allowing the spring to extend, upstream through the regulator and check valve.
