Hydronic Heating & Boiler Supplies

As system fluid enters through the inlet, (either straight or angle) the diffuser distributes flow evenly across the stainless steel, wire brush-like medium. Air bubbles, even micro air bubbles, stick to the brush filaments. Trapped air rises above the diffuser through a baffle where the air is then released through an opening at the top. Treated water then goes back into the system.

Series LF70A, LFL70A Hot Water Extender Tempering Valves are used in residential water supply applications to mix cold and hot water to extend capacity of water heater storage tanks and hot water boiler tankless heaters.

Specs

Lead Free Series LF150A Water Hammer Arrestors are used in residential applications to control water pressure shock and prevent water hammer conditions. 

Specs

The noise from banging pipes is caused by shocks of high speed water flowing in the piping system when a fixture is suddenly closed. Sudden stoppage of the water (a non-compressible liquid) flowing at a given pressure and velocity causes a surge or spike of water and is called water hammer.

Specs

Series B911, B911S Bronze Combination Fill Valve and Backflow Preventers are for use in commercial and residential hydronic heating systems to provide make-up water to the boiler, and prevent backflow when supply pressure falls below system pressure.

Specs

Series LFN36 Lead Free Water Service Vacuum Relief Valves are used in water heater/tank applications to automatically allow air to enter into the piping system to prevent vacuum conditions that could siphon the water from the system and damage water heater/tank equipment. 

Specs

Taco Air Scoop's enlarged design with internal baffles slows the water velocity in order to provide a noiseless, air-free hydronic heating, cooling or combination system, by efficiently separating out the air from the water in any of these systems.

Installed on water or stream radiators the Taco automatic coin vent is the ideal air purging device. The vent can also be manually shut-off by means of an internal ball check. The 417 coin vent is suitable for use in water and low pressure steam applications.

Specs

Taco Flo-Cheks are used in forced hot water heating systems to prevent gravity circulation during periods when the boiler is hot, but the space heating zone is not wanted. This makes it possible to use the heating boiler to maintain domestic hot water year-round. You can also use Flo-Cheks in systems with multiple circulator zones to allow heat to flow only into the zones that are calling for heat.
