The Atmospheric Vacuum Breaker is designed to prevent contaminants from entering the main water supply through sprinkler heads. It is not designed to be used as a mainline anti-siphon device.

Symmonsmixing valve

Ideal for use where lead free valves are required. Designed for installation on potable water lines to protect against both backsiphonage and back pressure of polluted water into the potable water supply. The Model 705 shall provide protection where a potential health hazard does not exist. Applications include indoor and outdoor meter box installations as primary domestic water protection. Standard lay length allows for retrofit of existing dual checks. Lead-free body and checks ensure safe drinking water while providing maximum corrosion resistance. Maximum Working Pressure: 175psi (12.1 bar).

In mixing applications where a controlled temperature outlet is required, the 3-way control valve (M/D) will modulate between the hot and cold inlet feeds (ports “B” and “C”) to mix your fluid to the desired specified temperature exiting the “A” port.

The TBV cartridge can be integrated into a 4-way manifold to monitor inlet flow and divert the fluid based on temperature. Cooler fluid goes through the valve bypass, while hotter fluid goes through the system’s cooler.

Federal law requires a proper backflow device to be installed on any watering system to prevent contamination of the supply; whether it be pump or city water. Check your local water authority for installation requirements & codes. In many rural areas; specific requirements for landscape irrigation systems may not be covered in local plumbing codes and/or enforcement may be limited. HOWEVER...limitation in local authority does not alter the basic requirement for protection of the potable water supply.

ThermOmegaTech’s thermostatic mixing valves/diverting valves use a thermal actuator to accurately proportion and maintain flow in response to temperature. These 3-way thermostatic valves are used in a variety of industrial, aerospace, & defense applications.

Installed in mixing mode, the mixing valve’s thermal actuator will sense the temperature to automatically proportion the flow of hot and cold fluid from two inlet ports to produce the desired outlet port temperature.

Wattsmixing Valve

Installed in diverting mode, the valve’s thermal actuator will sense the fluid temperature and automatically divert or switch the inlet flow to either of the two outlet ports depending on the valve’s specified temperature requirements.

Thermostatic Mixing/Diverting Valve Product Brochure Thermostatic Mixing/Diverting Valve Installation and Maintenance Instructions

The thermostatic mixing valve/diverting valve is designed to maintain or proportion flow based on temperature in mixing or diverting applications.

In diverting applications where the fluid must be directed from one section of a system to another, the thermal diverting valve (aka thermal bypass valve) will modulate inlet fluid temperature and divert return flow through a cooler/ heat exchanger or bypass it to a reservoir/ bypass loop when fluid temperatures are satisfied. This action assures rapid system warm-up, accurate control of fluid temperature, and reduced back pressure in the return.
