H17 Series BASO® Automatic Pilot Valves
The H17 Series BASO® pilot valves provide complete
shutoff in the event that the flame heating the
thermocouple is extinguished. Applications include
room heaters, infrared heaters, salamanders, and
refrigerators.
H17 models are also available with a higher ambient
temperature, up to a maximum of 149°C (300°F), for
use on commercial ovens, broilers, and other
applications.

Product Overview
Application
The H17 series valves provide complete shutoff in the
event that the flame heating the thermocouple is
extinguished. They are suitable for use with natural gas,
Liquefied Petroleum (LP) gas, manufactured gas, mixed
gas, or LP gas-air mixtures at pressures up to 35 mbar
(0.5 psi). The H17 is suitable for operation over a
temperature range of -40 to 66°C (-40 to 150°F) for
standard models. High temperature models are suitable
for operation over a temperature range of -40 to 149°C
(-40 to 300°F).
Description
H17 valves are compact, straight-through aluminum
valves with pipe sizes from 1/8 to 1/2 inch.
H17 valves do not have a flow interrupter, therefore,
gas flows to both the main burner and pilot burner (if
used) when the reset button is depressed. Where a
pilot is not used, the pilot outlet is omitted and the tip of
the thermocouple is inserted directly in the main burner
flame.
Mounting
H17 valves may be mounted in any position. This
permits the reset button to be located in the most
accessible location.
