Prevent catastrophic water backflow and protect your pumps with our Spring-Loaded Soft Pipe Check Valve from Atradesen.com.

🌟 Advanced Spring-Loaded Design
-
Install in ANY Direction (Horizontal or Vertical): Unlike gravity-dependent lift valves, this valve utilizes a highly sensitive 304 stainless steel spring. It guarantees a rapid, secure closure whether installed vertically, horizontally, or at any angle!
-
Barbed Ends for Soft Hoses: The stepped barb design allows for an effortless push-fit connection with soft tubing. No PVC glue required! (For high-pressure applications, securing with a hose clamp is highly recommended).
-
Premium Industrial Materials: Constructed with a UPVC shell, POM core, 304 SS spring, and EPDM O-ring. Rated for 10kg (1.0 MPA) pressure and perfectly safe for clear water and weakly corrosive liquids.
⚠️ Installation & Flow Guide (Crucial!)
Please read these Atradesen.com guidelines carefully before installing to ensure proper operation:
-
🚨 FOLLOW THE ARROW: This is a directional valve. You MUST install it so the printed arrow on the body matches your desired Water Flow Direction. Installing it backward will completely block the water flow!
-
Liquid Compatibility: Designed for clear liquids ONLY. Do not use with liquids containing solid particles or heavy debris, as they can get caught in the spring mechanism and cause the valve to leak.
-
Sizing: The size you select refers to the Inner Diameter (I.D.) of your soft hose.
