Model 400 Feeder # 20 Rate Of Feed Valve

Precise dosing starts with a properly functioning rate-of-feed valve, and this genuine #20 rate of feed valve keeps your Model 400 chemical feeder metering accurately. As the component that regulates how much chemical solution the feeder delivers, it sits at the heart of consistent, effective water treatment, making it one of the most important wear parts in the entire system. When it works as intended, dialing in a feed rate is straightforward and repeatable.

• Genuine Model 400 feeder #20 rate of feed valve
• Regulates the feeder's chemical dosing rate
• Direct-fit factory replacement part
• Restores accurate, repeatable metering
• Very lightweight at roughly 0.04 lbs
• Essential spare for chemical-feed systems

Over time, a rate-of-feed valve can wear, clog with mineral or chemical residue, or lose its adjustment precision, causing the dose to drift too high or too low. Either condition is a problem. Too little chemical undermines treatment effectiveness and can leave water inadequately conditioned, while too much wastes chemical and may create downstream issues. Swapping in the correct replacement valve brings dosing control back to specification so you can confidently dial in the feed rate your application requires, instead of fighting a worn part that will not hold its setting.

Built for continuous-duty feeders

Chemical feeders like the Model 400 are commonly used to introduce chlorine and other treatment chemicals into water systems at a controlled rate, so the integrity of the feed-rate valve directly shapes the result at the tap. Because it is a moving part in constant contact with feed chemicals, it naturally wears and benefits from periodic replacement as part of routine service rather than waiting for a failure to force the issue.

For operators and technicians who depend on reliable chemical dosing, keeping this genuine part on hand makes service quick and predictable. A fresh, correctly fitted valve helps maintain consistent, accurate treatment with minimal downtime and far less guesswork when dialing in the system, which is exactly what you want when results matter and time on site is limited. Inspecting the valve during routine service, and replacing it before it drifts out of tolerance, is a simple habit that keeps a feeder dosing on target between visits.
