Silent check valve is a type of check valve designed to minimize noise caused by the sudden closure of the valve disk. It is also known as a “nozzle check valve” or “spring-loaded check valve”. The valve body is usually made of metal or plastic and contains the other components of the valve.
This Type valve has a spring-loaded mechanism that controls the valve disk’s movement, ensuring that it opens and closes smoothly and silently. The spring provides a controlled closing speed, reducing water hammer and slamming noise.
Application of Silent Check Valve
Silent check valves are commonly used in water supply systems, wastewater treatment plants, and other applications where noise reduction is a concern. The nozzle is a small opening in the valve body that allows fluid to flow through. The check valve element is located inside the valve body and is designed to allow fluid to flow in one direction only. They are particularly useful in situations where water flow rates are high, such as in fire protection systems, and where backflow prevention is necessary.
The scope of application of a nozzle check valve can be in a wide range of industries, including oil and gas, شیمیایی, پتروشیمی, دارویی, food and beverage, and water treatment. These valves can be used in a variety of applications, such as pipelines, pumps, and compressors, to prevent backflow and protect equipment.
