| Navigator® Lead-Free Thermostatic Mixing Valves Better for the environment and safer for drinking water, Navigator Thermostatic Mixing Valves comply with all new lead-free requirements while maintaining the quality you have come to expect from Bradley. Bradley's Navigator Thermostatic Valves are American made and were the first lead-free mixing valve on the market. What are the benefits of the Navigator valve's single valve design? It is much less complex than a multi-valve system making it easier to set up and start up - especially in a recirculated system. An integral port allows the tempered water recirculation line to be attached directly to the valve body. As a result, the Navigator valve has fewer connections than a multi-valve manifold system. Fewer connections and universal mounting capability means reduced installation time. Navigator valves control the output temperature for variations in input temperature and pressure. This anti-scald protection is built in - another benefit of this compact uncomplicated line of valves. |
 |
Navigator® High-low valves High capacity systems Recirculation systems A high-low valve is best used when there is a fluctuation in usage - where there are both high and low flow requirements. |
 |
Navigator® Standard valves A standard valve is best used when there is a constant flow of water needed/required. |
 |
Point-of-Use Valves A point-of-use valve is attached directly to the shower or lavatory to control the water temperature and provide anti-scald protection. |
 |
Navigator® Emergency valves An emergency valve is used exclusively on emergency eyewash and drench shower applications to provide tepid water. Safety features include anti-scald protection and fixed cold water bypass ports to ensure cold water will keep flowing at all times. |

| Bradley's Navigator high-low valves use a single valve design to control water temperatures during both high demand and low demand. These valves can be used at the main water source or in remote locations such as a locker room. The valve maintains the temperature to within +/- 3 degrees no matter how much water is demanded. Bradley's Navigator High-Low valves are ASSE 1017 and CSA certified. | ||||||||

| NovaCare Complex, Philadelphia, PA NFL Training Facility Reduces Maintenance with Navigator® Thermostatic Mixing Valve NovaCare needed a valve that could deliver from five to 200 gallons of water per minute, and accurately maintain a preset temperature during periods when no water was being drawn from the system. Ken Rinear, a Bradley Corp. representative with Rinear Associates, Inc., recommended that the existing two-valve system be replaced with a Bradley high-low Navigator TMV (model HL-200), which could accommodate a higher capacity. The Navigator is a compact valve capable of providing tempered water for fluctuating high and low demand without the need for a second low-capacity valve. "Sizing and specifying the Navigator valve couldn't have been easier," noted Ray Murphy, the plumbing foreman. "Installing the single unit was fast and the valve hasn't required any maintenance since being installed - we're extremely impressed." |

| Save Time & Money Bradley's Navigator Recirculation Station is designed to take the guesswork out of installing a thermostatic mixing valve in a recirculation system. This pre-assembled, pre-tested recirculation station consists of a Navigator High-Low Valve combined with the components typically used in this type of system: piping assembly, inlet/outlet shut-off valves, pressure/temperature gauges, circulation pump, balancing valve, and a GFCI outlet mounted to an enamel-coated strut. The Navigator NRS simplifies the specification and installation to such a degree that no factory technicians are required for installation. It's that easy. |

| University of Hartford, West Hartford, Conn. Campus Improves Safety, Reduces Maintenance with TMVs Literally thousands of showers are taken each day in dorms and locker rooms on the University of Hartford campus. Since scald protection is a key issue, the school needed to replace single hot water tanks with tempering valves in its Village Apartment complex. In total, about 12 Bradley Navigator TMVs have been installed at the University. For efficiency, these master TMVs are installed near the hot water source. This eliminates the need for installing individual valves for each shower. The Navigator line of valves uses single-valve technology to blend hot and cold water to preset temperatures with pinpoint accuracy, providing better user protection. Preset temperatures are maintained within three degrees, and in the event that cold water supply is lost, the valves will shut off hot water to prevent scalding. "The new Bradley TMVs are working marvelously," Lou Perleoni, the University's head of plumbing services said. "I'm amazed by the lack of maintenance on these valves." Perleoni also mentioned that he appreciates the compact Navigator design and that cleaning the cartridge is not an issue. |

| The 15-minute rule: The current ANSI standard calls for emergency eyewash and drench showers to deliver tepid water for 15 minutes. This assures that a user won't be subjected to very cold water and possibly hypothermia or very hot scalding water and possibly skin burns. Therefore, a thermostatic mixing valve is needed to mix incoming hot and cold water to a tepid temperature. The Navigator EFX is designed for this very purpose. | ||||||||

| Not only does the Navigator maintain an accurate temperature, it also has an added safety feature. If the cold water stops, the Navigator prevents scalding by shutting down the hot water. If the hot water stops or the thermostat loses its charge, the valve's fixed cold-water ports keep the cold water flowing. | |

| Specifying valves When you're specifying thermostatic mixing valves, "How much water is needed?" is a critical question. And, it inevitably leads to another critical question. "What size valve do I specify?" Determining actual flow requirements is tricky. Only a small portion of faucets, showers and other fixtures in a large system are operating at any given time. Any valve selected to supply 100% of maximum demand would therefore be greatly oversized. Standard thermostatic mixing valves provide accurate control at higher flow rates. High-Low valves are designed to control temperature at both high and low flow requirements. Matching the valve with the flow requirements will then provide the most accurate and economical valve for the job. For several years thermostatic mixing valve manufacturers and system designers have successfully used a modified Hunter's Curve to determine the hot water requirements of various types of buildings. Originally used to size instantaneous heaters, this system provides accurate estimates of hot water usage. But, as with any system, the designer must account for any unusual or unique requirements. |

| Example: • 40-Room Nursing Home • Each room has 1 private basin. • Additionally there are 2 public lavatories, 2 showers, 1 bathtub and 1 service sink. • Inlet water pressure is 35 psig. Count fixture units using the values from Table 1: Hot Water Demand 40 rooms at .75 per basin = 30 2 public lavs at 1.0 per basin = 2 2 showers at 1.5 = 3 1 bathtub at 1.5 =1.5 1 service sink at 2.5 = 2.5 Total: 39 Fixture Units |

THE HUNTER'S CURVE METHOD
|
|
Referring to Graph 1 (above), 39 Nursing Home Fixture Units corresponds to Hunter's Curve "B" and a flow rate of 22 GPM. A High-Low valve is the best selection, in order to closely control temperatures at flows lower than 22 GPM. |
