1. When the pressure reducing valve, the outlet pressure is controlled to ensure that the outlet pressure is a stable value. The pressure reducing valve of the hydraulic press is connected in series with the load. The pressure regulating spring chamber has an external drain port, which adopts negative feedback of the outlet pressure. The valve port is normally open when not working, and the overflow valve is inlet pressure control...
