HydroLogic® Stealth-RO™ 300 Flush Valve Flow Restrictor - For Stealth-RO™ 300 Systems

HydroLogic® Stealth-RO™ 300 Flush Valve Flow Restrictor - Essential Flow Control for Membrane Flushing

The HydroLogic® Stealth-RO™ 300 Flush Valve Flow Restrictor is a precision flow-control component engineered specifically for Stealth-RO™ 300 Systems. By regulating the flow of water during the membrane flushing process, this restrictor ensures that the system operates within its optimal flow parameters — protecting the RO membrane from damage during flushing while maintaining the efficiency and consistency of the purification process. Replacing a worn or missing flow restrictor restores proper flush cycle performance and helps extend membrane service life.

Key Features & Benefits

• Precise flow regulation: Controls water flow rate during the flush valve cycle to maintain optimal system operating parameters for the Stealth-RO™ 300.
• Membrane protection: Proper flow restriction during flushing helps prevent membrane damage from flow surges or pressure spikes that can occur without a functioning restrictor.
• System-specific engineering: Designed exclusively for Stealth-RO™ 300 Systems — correct flow rating for this system's specifications.
• Extends membrane service life: Correct flush cycle flow management reduces fouling buildup and supports longer membrane service intervals.

Who Should Use This

Required for Stealth-RO™ 300 operators who need to replace a missing, damaged, or worn flush valve flow restrictor to restore proper flushing function and protect membrane performance.

Compatibility

For use with HydroLogic® Stealth-RO™ 300 Systems only.

Frequently Asked Questions

What happens if the flow restrictor is missing or damaged?

Without a properly functioning flow restrictor, the flush cycle may not operate at the correct flow rate — potentially allowing excessive waste water discharge, reducing product water efficiency, or stressing the RO membrane during flushing.

How do I know if my flow restrictor needs replacement?

Signs include excessive waste water flow, reduced product water output, or changes in the system's waste-to-product ratio. If the Membrane Power Flush Kit has been used and the flow restrictor was removed or lost, it should be replaced.

Is this the same restrictor used in the Stealth-RO™ 150?

No — this flow restrictor is specifically calibrated for the Stealth-RO™ 300 system. Do not interchange with Stealth-RO™ 150 components as the flow ratings differ.

Is this included with the Membrane Power Flush Kit?

The Stealth-RO™ 300 system ships with a Membrane Power Flush Kit. Consult your system documentation or contact HydroLogic® to confirm flush kit component details.
