Check Valves & Its Application, Mechanism, Benefits
Wastewater pumping systems require application of quality check valves for improved performance. While the industry sewage check valve is popular, the use of check valves are also used in other pumping-mechanism applications.
Check valves are a type of safety valve that allows liquids to flow in only one direction. The primary purpose of using check valves is to prevent reverse flow in the pumping system. Because of their main functionality, check valves are also known as Non-return Valves.
The application of check valves helps in improving the overall functionality of the pumping station system. If you are someone who is searching for quality check valves then make sure to read this blog till the end to have a proper understanding of check valves.
Applications of Check Valves
The simple design and versatile options of materials enable check valves to be used for several applications. Most commonly they are used in the wastewater management systems application.
They are also extensively used in irrigation and potable water applications. Some of the other applications includes –
- Mining
- Oil & Gas
- Process
- Food & Beverage
- Power Plants
- Pharmaceutical
The configuration of the component is mainly considered for choosing the specific use of check valves. Check valve installations in the pump-mechanism system is important for preventing damage of the system and enhancing its overall performance.
Alternatively, check valves are also used as a backup application in case the pump system encounters failure. With its application, engineers can get help in reciprocating pump functions and for enhancing compressors functions.
How does Check Valves operate?
Check Valves are flow sensitive and work basically on the principle of line fluid to open or close. The internal disc found in a check valve is responsible for liquid or gas flow to pass forward and enables opening the valve.
The disc starts to close off the valve when the forward flow reduces or reverses depending on its design. The overall construction of a check valve is simple consisting of only a few components such as the body, disc, seat and cover.
Based on varying designs, the check valve may have other components such as a disc arm, spring, stem hinge pin, elastomers, ball and bearings.
Benefits of using Check Valves
The use of check valves are very much essential in pumping station systems especially wastewater treatment pumps. The simple design and user-friendly operation allows check valves for different applications. Some of the obvious benefits that you can get from check valves are –
- They can be used as backup system in case of pump function failures
- They protect compressors and pump from damaging by preventing backflow
- Enables low pressure drop, hence, helping in energy saving
- Eliminates chatter and therefore, lowers the risk of abrupt valve failure
- Flexibility to adapt variable flow conditions
- Helps in sustaining pressure within the system
