The Drain Check Valve is an integral component of the air conditioner unit, and functions to prevent the backflow of condensate water, this valve allows condensate water to flow out of the system while preventing reverse flow, ensuring efficient drainage, and preventing potential water damage, it includes a mechanism that opens to allow water to exit when the unit is in operation and closes to prevent backflow when the system is inactive, maintaining optimal functionality and safeguarding air conditioning units from water buildup.Attributes:• Prevents backflow of condensate water.• Corrosion resistant for longevity.• Withstand to high pressure and fluid flow.• Protects against water damage.Applications: The Drain Check Valve is used to prevent the backflow of condensate water in the air conditioner unit, ensuring uninterrupted drainage preventing water damage, and maintaining system functionality.
