Principle of liquid prefill valve: in high pressure and large flow, it can play the role of unloading, and avoid the impact of unloading. The filling valve is generally used as the suction and discharge valve between hydraulic pressure and oil tank. When the large press is moving fast, the oil cylinder needs to add a lot of oil and automatically absorb oil to the oil tank. When slowly entering and pressurizing, the oil should be prevented from backchanneling the oil tank from the cylinder. In reverse, the oil can be discharged from the cylinder back to the tank.
 
Features: the liquid filling valve adopts spring-loaded disc-type cut-off structure, which can make the piston quickly fill and discharge under pressure. The liquid filling valve can also set pre-opening pressure, which has reliable sealing performance. Excellent processing, precision height, no leakage, good pressure holding performance. With its own slowly moving spool, it can effectively reduce the sound and vibration.
 
Check valve before and after the media pressure is close to balance and "saw" each other, disc and seat flap, some brittle materials (such as cast iron, brass, etc.) made of disc is broken. Prevention is to use a check valve with a ductile disc.
