Raypak Genuine OEM Bypass Valve Assembly Kit, 016194F

The Raypak 016194F is the genuine OEM bypass valve assembly kit for Raypak pool heaters, supplied by Raypak Inc. as a complete assembly rather than as loose components.

What the bypass valve does

Inside a Raypak heater, the bypass valve decides how much of the incoming water actually passes through the heat exchanger and how much goes around it. That balance is what keeps the exchanger working in its intended range across different pump speeds and plumbing setups. When the valve sticks, leaks or breaks, the heater loses that control, and the exchanger takes the consequences.

Before you order

Raypak uses different bypass assemblies across its heater ranges, and the available information does not list which models take this one. Check 016194F against the parts list for your heater. If the heater is old enough to need a bypass valve, it is worth looking at the pressure relief valve, the hi-limit control and the unitherm governor at the same time, all of which Raypak sells as separate parts.
