TOTO Spare Part: TT6501 – Flow Regulator in Stop Valve

Part Name:

• TT6501 – Flow Regulator in Stop Valve

Brief Description:

TT6501 is a flow regulator installed inside the stop valve of selected TOTO automatic faucets (sensor faucets). It regulates the volume of water passing through the valve, ensuring a consistent flow rate regardless of changes in supply pressure.

Main Uses:

• Maintains a constant water flow during operation.
• Reduces excessive water discharge caused by high water pressure.
• Helps save water while maintaining user comfort.
• Protects internal faucet components from pressure fluctuations.
• Supports proper performance of TOTO sensor-operated faucets.

How It Works:

The flow regulator is fitted within the stop valve. When water pressure increases, it restricts the opening to keep the flow rate nearly constant. When pressure decreases, it allows sufficient water to pass so the faucet continues to operate correctly. This provides a stable and efficient water supply.

Typical Applications:

TT6501 is used in selected TOTO automatic (sensor) faucets and related plumbing assemblies where a stop valve is provided for…
