Product Description

Silent check valve is a valve used to prevent fluid backflow. Its main feature is that it can effectively reduce or eliminate the water hammer noise generated when the valve is closed. The following is a detailed introduction to the silent check valve:
1. Working Principle
The silent check valve is specially designed to automatically open when the fluid flows forward, allowing the fluid to pass through; when the fluid stops or flows in the reverse direction, the valve closes quickly to prevent backflow. Its silent effect mainly depends on the slow closing structure of the valve, which can slow down the speed of valve closing, thereby reducing the noise generated by the water hammer effect.
2. Main Features
- Silent effect: Through the slow closing design, the impact noise when the valve is closed is reduced.
- Prevent backflow: Effectively prevent the reverse flow of fluid and protect pipelines and equipment.
- Low head loss: The internal flow channel design of the valve is optimized to reduce the resistance when the fluid passes through.
- Strong durability: Usually made of corrosion-resistant and wear-resistant materials, with a long service life.
3. Application scenarios
Silent check valves are widely used in the following fields:
- Water supply system: Prevent water backflow when the water pump stops, protect the water pump and pipes.
- HVAC system: Used to prevent hot or cold water backflow and maintain normal operation of the system.
- Industrial pipeline: In the chemical, petroleum, pharmaceutical and other industries, prevent the backflow of media from causing pollution or equipment damage.
- Fire protection system: Ensure that water does not flow back when the fire pump stops, and maintain system pressure.
