No Moving Parts.
Self-Cleaning Design.
The Flo-Trol® automatic flow control valves are designed to give constant flow over wide pressure ranges. This is a critical feature for protecting pumps and ensuring system efficiency.
The Secret: A self-cleaning flexible orifice (Buna-N) that varies in size with applied pressure. As pressure increases, the orifice constricts, maintaining a steady flow rate.
- ✅ Prevents Clogging: Flexible orifice design clears debris automatically.
- ✅ Maintenance Free: No mechanical parts to wear out or replace.
- ✅ Laser Marked: Easy identification of flow rates and direction.

Why Choose Flo-Trol?
💧 Save Energy & Water
By strictly limiting flow rates to specification, Flo-Trol prevents pump over-cycling and reduces water waste. This precise control is essential for green building compliance and operational cost reduction.
🛡️ Certified Safety
The Flo-Trol is NSF/ANSI 61 & 372 certified, meaning it is completely Lead-Free. It is safe for all potable drinking water applications, giving you peace of mind for residential and municipal projects.
🔧 Simple Installation
With its compact, all-stainless steel body and standard NPT threading, the Flo-Trol installs easily between the pump and the outlet. Its robust construction ensures it withstands harsh environments with zero maintenance.
Applications
Ideal for systems requiring constant flow rates:
Frequently Asked Questions
How does the Flo-Trol maintain constant flow?
It uses a self-cleaning flexible Buna-N orifice that automatically constricts as pressure increases. This keeps the flow rate steady within ±15% accuracy, regardless of pressure fluctuations between 15 and 125 PSI.
Is the Flo-Trol valve lead-free?
Yes. The Flo-Trol is constructed from 304 Stainless Steel and is NSF/ANSI 61 & 372 certified, meeting all requirements for lead-free plumbing components.
Does this valve require maintenance?
No. The Flo-Trol has no moving mechanical parts like springs or pistons to wear out. The flexible orifice is self-cleaning, meaning debris is automatically cleared during operation.
