Overview of Single Door Wafer Check Valve?
Single open door Wafer check valve refers to the valve that automaticallyopens and closes the valve disc depending on the flow of medium itself toprevent the reverse flow of medium.This check valve belongs to an automaticvalve,whose main function is to prevent the reverse flow of medium,preventpump and drive motor from reversing,and the discharge of container medium.It may also be used in the supply line of an auxiliary system where the pressuremay rise above the pressure of the system

The Difference Between Single Door and Double Door
The primary difference between single door and double door check valves lies in the number of doors or discs they have for controlling flow.
Single Door Check Valve: As the name suggests, a single door check valve has only one door or disc that swings or pivots to allow forward flow and closes to prevent reverse flow.
Double Door Check Valve: In contrast, a double door check valve has two doors or discs, one on each side of the valve body. These doors swing open independently to allow forward flow and close independently to prevent backflow. Each door typically operates with a hinge mechanism.
Single Door Check Valve: The single door design may result in slightly higher pressure drops compared to double door check valves due to the design constraints of accommodating only one door.
Double Door Check Valve: With two doors, double door check valves can offer lower pressure drops and smoother flow characteristics, especially in larger diameter pipes.
So Single door check valves are commonly used in applications where space and cost are primary considerations, such as residential plumbing, irrigation systems, and HVAC systems.
