Valve relief JCB JS330 25/221556 Aftermarket LNC0261, 21113-50306.
For safe drainage purposes.
When the pressure inside the pipeline reaches the set pressure of the overflow valve, the overflow valve automatically opens and discharges. When the pressure inside the pipeline decreases, the overflow valve automatically closes, stopping pressure relief, and providing safety protection for the pipeline.
Overflow valve is a hydraulic pressure control valve that mainly plays a role in constant pressure overflow, pressure stabilization, system unloading, and safety protection in hydraulic equipment. During assembly or use, the overflow valve may experience unexpected leakage due to damage to the O-ring or combination sealing ring, or loose installation screws or pipe joints.
Attention: If the cone valve or main valve core is excessively worn or the sealing surface is in poor contact, it will also cause excessive internal leakage and even affect normal operation
