Non Slam Swing Check Valve
A non-slam swing check valve is a type of check valve that prevents backflow in a pipeline by using a swinging disc that opens and closes in response to the flow of fluid. The valve is designed to prevent “water hammer,” which is a sudden surge of pressure caused by the rapid closing of a valve. Non-slam swing check valves are commonly used in systems where there is a risk of water hammer and in applications where the pressure drop across the valve is relatively low.
Parts
- Valve body
- Disc
- Hinge pin
- Seat
- Spring
- Cover
- Stem
- Actuator
Advantages
- The valve is designed to prevent “water hammer,” which is a sudden surge of pressure caused by the rapid closing of a valve. This can help protect the pipeline and equipment from damage.
- Non-slam swing check valves are designed to have a relatively low pressure drop across the valve, which means that the pressure loss caused by the valve is minimal.
- Non-slam swing check valves have simple design and easy maintenance.
- They are typically made from durable materials such as metal or plastic, which makes them suitable for use in a wide variety of applications.
- They can be used in a wide range of applications, including water, oil, gas, and chemical systems.
- Non-slam swing check valves are relatively inexpensive and easy to install, making them a cost-effective option for many applications.
