SECTION 221119 - Thermostatic Mixing Valves
BRADLEY THERMOSTATIC MIXING VALVES
Bradley Corporation, a leader in the manufacture of fixtures and plumbing products, produces four lines of thermostatic mixing valves (TMVs). Bradley Navigator® High-Low thermostatic mixing valves are ideal for applications where off-peak demand is very low. Valve design handles both high and low demand with a single device. Navigator Standard thermostatic mixing valves are recommended for applications where demand is fairly constant even during off peak times. Navigator Emergency thermostatic mixing valves are for use with emergency eyewash, drench showers, and combination emergency wash units. Emergency thermostatic mixing valves provide tepid water as required by ANSI/ISEA Z358.1. Bradley is the only manufacturer of both emergency fixtures and valves. Navigator Point-of-Use thermostatic mixing valves are intended for use with a single shower or sink faucet.
Responding to recent legislation, Bradley Navigator line of thermostatic mixing valves are manufactured from lead-free brass castings and bar stock to comply with the most stringent rules that require less than one-quarter of one-percent lead content.
Architects, engineers, and specifiers
look to Bradley Corporation for innovation in design and leadership in the
development of environmentally conscious products. Bradley Corporation, a member of the U.S.
Green Building Council, the Wisconsin Green Building Alliance, has several
products earning certification by Greenguard Environmental Institute, and
Greenguard Children and Schools program.
Bradley makes it easy to specify products with helpful information tools on an advanced website, and a seasoned customer service staff. Easy-to-use sizing software, available on Bradley's website, allows engineers to quickly determine the correct size Thermostatic Mixing Valves. Bradley is the industry leader in the manufacture of premium quality commercial plumbing fixtures, valves, TMVs and washroom accessories that appear in the following CSI MasterFormat 2004™ Sections:
