Filling valve principle: under high pressure and large flow, it can play the role of unloading and avoid unloading impact. The charging valve is generally used as a suction and drain valve between the straight hydraulic and the oil tank. When the large press moves quickly, the oil cylinder should be supplemented with a large amount of oil and automatically suck the oil into the oil tank; when moving forward and pressurizing slowly, prevent the oil from overflowing from the oil cylinder to the oil tank. When reversing, the oil can be drained from the cylinder to the oil tank.

Filling valveFeatures: The filling valve adopts a spring-loaded disc cut-off structure, which can make the piston fill and discharge quickly under pressure. The filling valve can also set the pre-opening pressure, and the sealing performance is reliable. Well-processed, highly accurate, no leakage, good pressure holding performance. The spool moves slowly, which can effectively reduce dynamic noise and vibration. Filling valve is widely used in forging machinery, high-speed punch, press, injection molding machine and other machines. In forging machinery, the cylinder of the press can play the role of rapid oil injection and oil discharge. Under high pressure and large flow, it can play an unloading role and avoid unloading impact. The filling valve is usually used as a suction and drain valve between the hydraulic and the oil tank. When the large press moves quickly, the oil cylinder should be supplemented with a large amount of oil and automatically suck the oil into the oil tank;Filling valvePrevent oil from overflowing from the cylinder to the tank when slowly advancing and pressurizing. When reversing, the oil can be drained from the cylinder to the oil tank.
Charge valve note:
1. When installing the check valve, pay special attention to the flow direction of the medium. The normal flow direction of the medium should be consistent with the direction of the arrow indicated on the valve body, otherwise the normal flow of the medium will be cut off.Filling valveThe bottom valve should be installed at the bottom of the pump suction pipe.
2. When the check valve is closed, surge pressure will be generated in the pipeline, which will cause damage to the valve, pipeline or equipment in severe cases. Especially for large-diameter pipelines or high-pressure pipelines, the check valve selector should be highly valued.
3. The check valve is only used as a one-way on-off valve,Filling valveTo prevent the fluid medium in various pipes or equipment back flow.
