CSA Rated. Standard Models are self-closing T&P Relief Valves for Water
Heaters up to 105,000 BTU/Hr.
Watts Series SL100XL, L100XL , LL100XL and LLL100XL have extended
inlet shanks for use with the new generation of water heaters containing
extra thick insulation. These valves eliminate the use of an extension
nipple required with standard shank length models.
The combined 2-in-1 Temperature & Pressure relief valve provides the
least expensive and proven means for protection against both excessive
temperature and pressure emergency conditions.
Watts Self-closing combination T&P relief valves are design certified,
rated and listed by CSA to the requirements of ANSI Z21.22; and by the
National Board to the requirements of ASME Section IV.
They provide fully automatic temperature and pressure relief protection
for hot water storage tanks and heaters up to 105,000 BTU/Hr.
The temperature sensing element must be immersed in the water within
the top 6" (152mm) of the tank. Male inlet and female outlet. Temperature
relief 210°F (99°C). Standard setting 75, 100, 125, 150psi (5.3, 7.0, 8.8,
10.6 bar).
