Check valves are one-way control systems. They prevent the fluid from moving in any but the designated direction. As the fluid passes through the check valve, it opens up. Reversing the flow of fluid, however, closes the valve. A water check valve refers to a check valve dedicated to this function for water – both pure and waste.
Applications
Water check valves are a mechanism designed to prevent backflow. They do not require any activation or involvement from outside. Placement within pipes and water/sewage systems at specified points allows them to operate effectively and efficiently to negate the water from returning back the way it came.
Such qualities are the major reason for its employment by various industrial concerns including the following:
- Food and Beverage
- Mining
- Oil and Gas
- Pharmaceutical
- Power
- Processing
It is important to remember the different types of water check valves before installation. Configuration plays a significant role. An installer, for example, does not place a ball check valve, in the same direction as he or she would a swing check valve. Moreover, a low-tension spring check valve is more effective for handling toxic or dead fluids; a swing-type check valve is more suitable for freshwater applications, and a spring-loaded or cage poppet-style check valve is better for submersible pump applications
The Importance of a Water Check Valve
Check valves are an important part of water pump systems. In industrial and residential use, they work hard to ensure the water moves in one direction only. In a wastewater system, it keeps the fluid flowing in the right direction. In a water well or pipe, this one-way action can prevent the backing up or reversal of sewage water into clean pipes. This action by a properly functioning water check valve prevents intermingling and contamination. By performing this action for a well or water system, it can ensure the integrity of the water flowing through the pipes.
