Reverse Osmosis Check Valve

Description

Reliable Protection for Your Water Filtration System

The Filpure Reverse Osmosis Check Valve is a small but essential component that keeps your RO system running smoothly, safely, and efficiently. Installed on the outlet line of the reverse osmosis membrane, this one-way valve prevents purified water from flowing backwards into the membrane housing. This protects the membrane, maintains correct pressure, and allows the automatic shutoff valve to function properly.

By ensuring that your RO system closes correctly when the storage tank is full, the Filpure Check Valve helps prevent unnecessary water waste while supporting long-term system performance. It is designed for both domestic and light commercial systems and is fully compatible with most standard RO units.

Key Features

✔ Backflow Prevention
Stops reverse flow to protect the membrane and maintain stable filtration pressure.

✔ Supports Automatic Shutoff Function
Ensures correct tank pressure so the RO system shuts off when the tank is full.

✔ Leak-Free and Durable
Engineered from high-quality materials for long-lasting system safety.

✔ Universal Compatibility
Suitable for most reverse osmosis systems using 1/4 inch or 3/8 inch tubing.

✔ Easy Push-Fit Installation
Quick to install without tools, ideal for home or office RO units.

✔ Built for Australian Water Conditions
Performs reliably under typical Australian household water pressure.

Available Sizes

• 3/8 inch Tube Check Valve (Model: 38TCV)
  • 1/4 inch Tube Check Valve (Model: 14TCV)

How the Check Valve Works

During filtration, the check valve remains open, allowing purified water to move into the RO storage tank. When the tank fills, pressure increases and the check valve closes. This isolates the membrane and allows the automatic shutoff valve (ASO) to stop the system.

When water is used and tank pressure drops, the check valve opens again, restarting the filtration cycle. This process ensures:

• Correct flow direction
  • Consistent membrane protection
  • Efficient water production
  • No backflow into the filtration system

Every reverse osmosis system requires a functional check valve to operate properly and maintain long-term efficiency.
