The ASCO Series HV434 is a family of low-temperature, stainless-steel shutoff valves with proof of closure for on-off or gas pilot control of commercial and industrial gas burners in harsh environments. The valves combine a unique double-disc design with a rugged 303 SST GO™ Switch to provide electrical indication of "closed" position. Their low-power DC peak-and-hold constructions reduce energy consumption to 0.85 W (hold). The valves design with large pilot orifice provides consistent and reliable operation. Suitable for applications such as tank heaters, line heaters, incinerators and flare stacks.
