The 1/4" RO Check Valve is designed to prevent reverse water flow in reverse osmosis (RO) and RO/DI filtration systems. This compact, inline valve allows water to flow in one direction while preventing backflow, helping protect your RO system and maintain proper operation.

A check valve is also an essential component for the proper operation of an Automatic Shut Off Valve (ASOV) in RO systems. It prevents water from flowing backward through the membrane's product water line, allowing the automatic shut off valve to function correctly when the storage tank is full or water production is no longer needed.

Ideal for aquarium RO/DI systems, water filtration setups, and other applications using standard 1/4" RO tubing.


Features:

  • Prevents reverse water flow and backflow
  • Essential for proper Automatic Shut Off Valve (ASOV) operation
  • Compatible with standard 1/4" RO tubing
  • Ideal for aquarium RO and RO/DI filtration systems
  • Helps maintain proper water flow direction
  • Compact inline design for easy installation
  • Suitable for new installations and replacement applications

Installation: Install the check valve in the correct direction of water flow, following the directional arrow on the valve body.
