2 H17 Series BASO Automatic Shutoff Pilot Gas Valve Product Bulletin
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, LP gas, or LP gas-air mixtures at pressures up
to 0.5 psi (35 mbar). The H17 is suitable for
operation over a temperature range of -40 to 150°F
(-40 to 66°C) for standard models. High temperature
models are suitable for operation over a temperature
range of -40 to 300°F (-40 to 149°C).
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.
