Buying Guide
What size is right for my system? For Rainbow feeder inline systems, 1/2-inch and 3/4-inch valves cover most residential and light commercial setups. Confirm the feeder model (320, 322, 300-29X) to ensure fit. How do I install safely? Use PTFE tape on threaded connections, hand-tighten, and avoid overtightening to prevent cracks. Do I need a valve designed for chlorine vs chlorine/bromine? Some models emphasize compatibility with Rainbow chlorine/bromine feeders; verify chemical compatibility with your feeder’s requirements. What about durability? Look for corrosion-resistant plastics and robust seals to minimize leaks and extend service life. Are there any compatibility caveats? Some replacements may fit multiple Rainbow configurations, but always match model numbers and inlet/outlet threads to your specific setup. What about maintenance? Choose valves with accessible components for easier inspection, cleaning, and replacement without disassembling the entire feeder.

FAQ
- What is a soft wash proportioner valve?
An adjustable valve used to control the mix of bleach or other chemicals with water in soft wash systems, ensuring consistent dilution and flow to the inline feeder or manifold. - Which valve size should I choose for a Rainbow feeder?
Choose based on your feeder’s inlet/outlet size and the system design; common options are 1/2″ and 3/4″ for Rainbow inline feeders in residential setups. - Is over-tightening a valve a concern?
Yes. Over-tightening can crack threads or seals; always hand-tighten and use appropriate thread sealant as recommended by the manufacturer. - Can these valves fit multiple Rainbow models?
Some valves list compatibility with 320, 322, and 300-29X models; always verify exact fitment against your feeder’s model number. - Do I need a metering valve or a control valve?
A metering valve provides precise chemical dilution; a control valve focuses on regulating water flow. In many systems, a combined or integrated valve serves both roles; confirm with your installation guide. - What maintenance is required after installation?
Periodic inspection of seals, cleaning of inlet/outlet threads, and replacement of worn seals or gaskets to prevent leaks and maintain accurate dosing.
