What Media Are Suitable for Check Valves?
Check valves, also referred to as non return valves, are the key players of numerous fluid systems, as they permit the flow of the fluid in one direction and block its backflow. A sound understanding of what kind of medias are compatible with check valves is necessary in order to make sure that the equipment works properly and lasts long. In this article, we shall discuss various media that one can easily control using the check valve.
Understanding Check Valves
Check valves are the ones, which regulate single-direction flow in transport systems. They resist backflow, the consequences of which could be system damage, contamination, and inefficiencies. Besides, these valves are popularly used in such spheres as water treatment, oil, and gas, and in the HVAC sector.
Types of Check Valves
Swing Check Valves: When working with lower flow rates, these valves are the best choice as they use a swinging disc to regulate the flow.
Ball Check Valves: Herein, a ball rolls inside the valve body, leaving no space for the backflow to happen, hence achieving the task of sealing reliably and not allowing any return of the fluid.
Wafer Check Valves: Easy to install and with very low weight, wafer check valves are indeed the best choice for applications where the space is critical.
Suitable Media for Check Valves
1. Water
Water is one of the media, that is being used most often with check valves. Whether in municipal water supply systems, irrigation, or industrial processes, check valves assure that water flows in the direction intended. Stainless steel check valves are very good at their job in water locations, due to their resistance to corrosion and their very nature of durability.
2. Oil
The oil and gas industry uses check valves to counter the potentially damaging effects of backflow in pipelines. TWT has some stainless steel check valves of high quality that can handle the different kinds of oil, such as crude oil and refined products, applicable in multiple areas.
3. Gas
Gas pipes are used to control the gas flow and thus avoid gas flowing back in the system. The stainless steel check valves are one ultimate option for sealing capabilities; they can be used in high-pressure gas applications.
4. Chemicals
One of the commonly used check valves is found in the industries managing the flow of chemicals. Check valves installed in chemical plants or sewage plants ensure that the backflow and thus the infectious substances do not reach there from the next process. Corrosion-resistant materials like stainless steel and the well-chosen sealing materials such as EPDM and PTFE are the basis for this broad applicability in resistance to various media like chemicals.
5. Slurries
In sectors like mining and wastewater treatment, check valves still play a crucial role in the handling of slurries—solid-and-liquid blends. Such cases require the use of solid valves that can bear the brunt of harmful materials and still work well. TWT’s swing check valves and ball check valves are the optimal choices for slurry applications, providing consistent performance even under extreme conditions.
