Series 3L and 53L are used for protection against excessive pressure
on domestic storage tanks or tankless water heaters. Similar in
construction to Watts Model 10L, the Model 3L has no temperature
relieving element. Model 53L has the basic design as Model 3L
except it is furnished in
1
⁄2" (15mm) size and does not comply
with A.S.M.E. requirements. Pressure range is 75-150psi (5.2-10.3
bar). Series 3L and 53L come in standard settings of 75, 100, 125
and 150psi (5.2, 6.9, 8.6 and 10.3 bar). These Pressure Relief Valves
are popularly used in conjunction with the Model 210 gas shutoff
valve on gas water heaters to shut off gas to heater if water heater
temperature exceeds 210°F (99°C).
