Zoomlion Concrete Pump Water Pump Overflow Valve For BZ720CS
The BZ720CS relief valve is developed by Zoomlion with advanced technology and strict quality standards, which is highly compatible with Zoomlion water pumps. It is an essential part to maintain the normal operation of the water pump system.
Premium Materials: High-quality metal alloys are used for its main body, which endows it with excellent corrosion resistance and high strength, ensuring a long service life even in harsh working conditions.
Sophisticated Design: The internal structure is precisely engineered. It adopts a unique spool and spring combination design. The spool is processed with high-precision machining technology, which can move smoothly and accurately control the pressure. The spring is carefully calibrated to provide the appropriate elastic force, ensuring the stable operation of the valve.
Pressure Sensing: The BZ720CS relief valve is highly sensitive to the pressure changes in the water pump system. When the system pressure rises to the preset opening pressure value, the valve senses the pressure change instantaneously.
Pressure Relief: Driven by the excessive pressure, the spool overcomes the elastic force of the spring and moves to open the valve port. Then, the fluid in the system is discharged through the valve port to the low-pressure area, reducing the system pressure.
Pressure Stabilization: As the system pressure drops to the preset closing pressure value, the spool returns to its original position under the action of the spring, closing the valve port and stopping the pressure relief process. In this way, the system pressure is maintained within a safe and stable range.
