Boiler Feed, Backflow Preventer & Combination Valves

To Automatically Maintain System Fluid with Added Protection

Taco Boiler Feed Valves have set the standard for dependable service. The Backflow Preventer offers added protection, preventing the system from emptying if supply pressure should fail. Coupling dependable service with added protection into one quality product is Taco’s Combination Boiler Feed & Backflow Preventer Valve. The Dual Control combines the Boiler Feed with an in-line Pressure Relief Valve.

These valves automatically feed water to a system whenever pressure in the system drops below the pressure setting of the valve. The dual control combines the boiler feed valve with an in-line pressure relief valve connected at the outlet end. The backflow prevents contamination of the potable water system if supply pressure should fail.
