How to determine the installation location of the check valve? What is the difference between installing a check valve before the pump and installing one after the pump, and where is pre-pump installation applicable? Check valves are usually used in conjunction with other valves. Where should a check valve be installed when used in conjunction with other valves?

Pump discharge line: Check valve is often installed on the discharge side of the pump to prevent backflow when the pump is not running. This helps keep the pump primed and prevents backflow through the system.

Pipeline system: Check valves can be installed in the pipeline system to prevent backflow and ensure one-way flow of fluid. They are typically used in applications where backflow could cause damage or interrupt the process.

Water and wastewater systems: Check valves are often installed in water and wastewater systems to prevent backflow and maintain the desired flow direction, especially in sewage systems and drainage lines.

Heating and cooling systems: Check valves are used in heating and cooling systems to ensure that the flow of water or coolant remains in the intended direction, preventing backflow and potential damage to equipment.

Hydraulic system: In the hydraulic system, check valves are installed to control the flow of hydraulic oil and prevent backflow, ensuring that the system operates as expected.

When installing a check valve, it is important to consider factors such as the type of check valve (such as swing check valve, lift check valve, or ball check valve), the flow characteristics of the system, and the specific requirements of the application. Additionally, check valves should be installed according to manufacturer recommendations and industry standards to ensure proper operation and performance.
