2 H19 Series BASO High Pressure Safety Pilot Valves Product Bulletin
Product Overview
Application
The H19 Series BASO high pressure safety pilot valves
provide safe lighting and complete shutoff of pilot and
main burner gas. They are suitable for use with natural
gas, Liquefied Petroleum (LP) gas or LP gas-air mixtures,
at pressures up to 25 psi (1.72 bar [172 kPa]). The H19 is
also suitable for operation over a temperature range of
-40 to 150°F (-40 to 66°C). The H19TB is suitable for
operating pressures of 15 psi (1.03 bar [103 kPa]) and
temperatures range of -40 to 225°F (-40 to 107°C).
IMPORTANT: Care should be taken to ensure the
valve is installed in applications where
operating pressures in excess of
25 psi (1.72 bar [172 kPa]) are not
expected to develop.
Description
H19 valves are 100% shutoff devices with compact,
cast aluminum valve bodies. When lighting the pilot
burner, the reset button must be depressed. On
models with flow interruption feature, gas flows only to
the pilot during lighting operation. Models without flow
interruption permit gas to flow to both the pilot and
main burner.
Mounting
H19 valves may be mounted in any position. This
permits the reset button to be located in the most
accessible location. See Figure 3.
