N.R.V for Membrane Housing – 1/4″ 1/8 ”(ELBOW TYPE)

The  N.R.V (Non-Return Valve) for Membrane Housing is a compact one-way valve designed to prevent backflow in RO (Reverse Osmosis) systems. Installed at the outlet of the RO membrane housing, it ensures that purified water flows only in the intended direction while stopping reverse pressure from flowing back into the membrane. This protects the membrane, maintains system pressure, and ensures stable RO performance.

Key Features

• Prevents backflow into the membrane housing

• Protects RO membrane from reverse pressure damage

• Standard 1/4″ & 1/8” connection compatible with most RO membrane housings

• Durable and corrosion-resistant construction
