A tank valve in an RO (Reverse Osmosis) pressure tank is a critical component that controls the flow of water between the RO system and the storage tank. It ensures efficient filling and dispensing of purified water from the pressure tank. Here’s an explanation:

Function of a Tank Valve:

1. Connection Point:
   • The tank valve connects the RO storage tank to the rest of the RO system, allowing water to flow in and out.
2. Flow Control:
   • When the tank is filling, the valve allows water to enter the tank under pressure.
   • When the faucet is opened, it allows stored water to flow out of the tank to the faucet.
3. Shutoff Capability:
   • The valve can be manually turned off to disconnect the tank from the system for maintenance or troubleshooting.

Design and Features:

1. Material:
   • Typically made from food-grade plastic or brass, ensuring durability and safety for drinking water.
2. Threaded or Push-Fit Connection:
   • Most valves have threads to securely attach to the tank outlet, while the other side has a push-fit connection for easy tubing attachment.
3. Operation:
   • Includes a lever or knob to open or close the flow of water.

Why It’s Important:

• Prevents leaks and ensures a tight seal for pressurized water.
• Allows for easy maintenance, such as replacing the tank or filters without affecting the system.
• Ensures consistent water pressure for smooth operation of the RO system.
