Watts 0063190 Preventer

When you're piping in a boiler feed line or setting up laboratory equipment, the Watts 0063190 BBFP delivers the heavy-duty backflow protection your system requires. This 1/2 inch backflow preventer features a durable forged brass body and stainless steel internal parts designed to handle continuous pressure up to 175 PSI. The dual-check design utilizes an intermediate atmospheric vent to safely discharge polluted water if a downstream check fouls, preventing cross-contamination in non-potable heating and processing applications. Rated for temperatures up to 250°F, this dual check valve with atmospheric vent is a staple for hydronic technicians who need reliability in tight spaces. Its compact profile and union connections simplify installation and field service, while the integrated strainer protects the rubber check valve seats from debris-related failure. For contractors managing hydronic heating systems, this valve provides the necessary barrier between system fluids and the supply line without the bulk of larger RPZ assemblies.

• Forged brass construction with stainless steel internals ensures long-term durability in high-temp hydronic environments.
• Intermediate atmospheric vent provides a visual signal of check failure, maintaining critical system safety.
• True line-sized design allows for maximum flow recovery with minimal pressure drop across the assembly.
• Union connections facilitate fast removal and replacement during routine maintenance or system flushes.
• Non-potable compatibility makes it the ideal choice for boiler feed lines, processing tanks, and sterilizers.

Can the Watts 0063190 be installed in a vertical orientation?
Yes, the Series BBFP is designed for both horizontal and vertical up-flow installations, provided the atmospheric vent is positioned to drain properly.

What should I do if the atmospheric vent is constantly dripping?
A constant drip usually indicates debris is fouling the first or second check seat. You should isolate the valve, use the union connections for removal, and clean the internal seats and strainer.

Is this model compliant with lead-free requirements for drinking water?
No, the 0063190 is intended for non-potable water applications only. For potable water or "safe drinking water" applications, a lead-free (LF) model must be used.
