Robertshaw 1720-008 Valve Assembly

The Robertshaw 1720-008 is a professional-grade thermomagnetic safety valve engineered for critical gas flow interruption in commercial cooking and heating applications. This TS11J series assembly includes both the magnet and the valve body, featuring a 1/4" NPT inlet and outlet for standard piping integration. Designed for high-heat environments, it maintains operational integrity within an ambient temperature range of 32°F to 300°F. The magnet assembly relies on millivoltage generated by a thermocouple; upon pilot outage, the drop in voltage allows the internal spring to overcome magnetic force, instantly closing both the pilot and main gas ports. This Type J safety valve is a drop-in replacement for specific Vulcan Hart 714267 and Hobart 705387-0000A units, ensuring precise flame failure protection. With its 0.5 PSI maximum pressure rating, the 1720-008 valve assembly provides the reliability required by veteran technicians for industrial ovens, infrared heaters, and RV gas appliances.

• Precise Gas Shut-off: Reliable thermomagnetic operation ensures immediate fuel cutoff during pilot failure to prevent gas buildup.
• High Temperature Rating: Built to withstand ambient temperatures up to 300°F (149°C), ideal for heavy-duty commercial kitchen lineups.
• Broad Compatibility: Direct replacement for numerous OEM parts from Vulcan Hart, Hobart, and Jade Range.
• Robust Construction: Features 1/4" NPT pipe connections for the body and 1/4" tubing connections for the pilot inlet and outlet.

What causes the Robertshaw 1720-008 to fail to hold? Failure is typically due to a weak thermocouple not generating sufficient millivoltage or a buildup of carbon at the magnet contact point. Ensure your thermocouple is properly seated and heating before replacing the valve.

Is this valve compatible with LP and Natural Gas? Yes, this safety valve is designed for use in gas systems requiring a millivolt safety interlock, provided the pressure does not exceed 0.5 PSI.

Can I replace just the magnet instead of the whole assembly? While the magnet can sometimes be sourced separately, the 1720-008 is a complete body and magnet kit to ensure a factory-sealed, leak-free installation.
