Auto shut off valve for water purification system

The AV-4 Four-Way Valve is a compact, reliable component designed to streamline flow control in reverse osmosis (RO) water purification systems. At Pure Water 4 Life, we recommend the AV-4 for its simple operation, durable construction, and proven performance in both residential and light commercial water filtration setups.

Product Overview

The AV-4 valve efficiently manages the flow of water through four key ports—typically for inlet, outlet, drain, and tank. It plays a vital role in maintaining pressure balance, preventing backflow, and automating shut-off functions in RO systems, without the need for electricity or complex controllers.

Key Features

• Four-Way Flow Control
  Designed for use in RO systems, this valve routes water through four essential pathways, helping your system run smoothly and efficiently.
• Automatic Operation
  Powered by system water pressure, the AV-4 valve eliminates the need for electronic timers or sensors, simplifying your filtration setup.
• Durable, Food-Grade Materials
  Built from non-corrosive, high-quality plastics suitable for contact with drinking water and resistant to scale, wear, and chemicals.
• Compact Design
  Its small footprint makes it perfect for tight installations under sinks or in compact filtration units.
• Easy Integration
  The AV-4 is compatible with most standard reverse osmosis systems and storage tanks, making upgrades or replacements simple.
