1. The oil that comes out of the pump without any processing is called primary oil, or power oil. The oil that passes through the electro-hydraulic converter is called secondary oil; it is generated when an electrical signal is sent to the electro-hydraulic converter, which in turn produces a corresponding pressure of secondary oil. This secondary oil serves as a signal for the throttle spool valve. It has no effect on the double-port quick shut-off valve; the quick shut-off valve uses a single flow of oil. 2. Generally, an electro-hydraulic converter converts a 4-20mA electrical signal into an oil pressure signal of 0.15-0.4MPA; the oil pressure of 0.15-0.4MPA downstream of the electro-hydraulic converter is referred to as the secondary oil pressure ； The secondary oil pressure has no effect on the speed-control valve used to regulate the throttle.
