Eclipse 200 LT valves are manually opening valves that automatically shut off the gas
supply to a combustion system when any interlocking limit switch opens. The valve
handle cannot be reset until the condition
causing the open switch is corrected and all
limit switches are closed. Typical limit
switches include air pressure, gas pressure,
temperature limit, and flame monitoring contacts. In the event of a power failure, the
valve immediately closes.

Series 200 LT valves include two visual indicators of “open” or “closed” position: a red
“flag” visible in the plastic dome on top of the
valve; and the reset handle position as indicated by cast markings on the operator
case. These valves also include two SPDT
micro-switches that can be used for auxiliary
circuits. Two contacts are made when the
valve opens, and two are made when the
valve is closed.
