Ductile Iron Slow Close Slient Check Valve For Water Pipeline System Use
Product introduction:
300X Series slow closing slient check valve is a common valve equipment used for fluid control and prevention of backflow in pipeline systems.
It adopts the principle of hydraulic slow closing, which controls the opening and closing of the valve through the pressure difference of the fluid itself. When the fluid flows normally in the pipeline, the valve is in an open state, allowing the fluid to pass through. Once the fluid flows in the opposite direction, the valve will immediately close to prevent backflow. When the valve is closed, the hydraulic slow closing device inside the valve plays a buffering role, avoiding the water hammer phenomenon that occurs when the valve is closed.

Product features:
1. Efficient check function: The 300X slow closing check valve has a reliable check function, which can effectively prevent fluid backflow, protect the safety and normal operation of the pipeline system.
2. Buffer and pressure reducing effect: The hydraulic slow closing device inside the valve can buffer the water hammer phenomenon generated when the valve is closed, reducing the impact on pipelines and equipment.
3. Quick closure and reliability: Valves have the characteristic of quick closure, which can quickly respond to changes in backflow pressure and ensure that the valve is completely closed in a short period of time to prevent backflow.
4. Simple and reliable structure: The 300X slow closing check valve has a relatively simple structure, reliable operation, long service life, and is relatively easy to maintain and repair.
5. Wide application: it is used in municipal water supply, drainage systems, industrial pipelines, fire pump water supply systems, and other fields. Common application scenarios include water treatment plants, sewage treatment plants, fire protection systems, industrial production processes, and other situations that require prevention of backflow.
