Robertshaw 1720-802 Magnet Head Assembly

The Robertshaw 1720-802 is a critical TS "K" safety magnet head assembly designed for high-performance gas flow regulation in commercial and residential kitchens. Engineered for use with 1710 series valve bodies, this thermomagnetic safety valve components acts as a fail-safe by automatically cutting gas flow upon pilot flame failure. Unlike the "J" series, the 1720-802 is a pilot outlet only configuration, making it the standard choice for specific BJWA, FD, and GS series thermostats. This kit provides a complete field solution, featuring a 1/8" pipe tap head with included fittings for 3/16" and 1/4" compression tubing. This assembly ensures flow interruption, preventing main burner gas release while the reset button is engaged. With an ambient temperature rating up to 300°F, it is built to endure the high-heat environments of commercial ovens and infrared heaters. Its thermocouple-actuated magnet ensures millivolt-sensitive reliability, providing the precise safety shut-off required for professional-grade gas cooking controls.

• Universal Compatibility: Engineered to integrate seamlessly with 1710 series valve bodies and high-demand gas safety valves.
• Complete Installation Kit: Includes the magnet head, diaphragm, valve spring, gasket, and high-tensile assembly screws for immediate field replacement.
• Internal Flow Interruption: Enhances safety by ensuring no gas migrates to the main burner during the manual reset phase.
• Broad Application Range: Optimized for commercial fryers, brooders, and recreational vehicle gas appliances.
• Standardized Pilot Fitting: Tapped for 1/8" pipe and adaptable to common pilot tubing sizes, reducing the need for additional adapters.

• Can I use the 1720-802 to replace a 1720-801? No. The 1720-801 is a "J" model (inlet and outlet), while the 1720-802 is a "K" model (outlet only). They are not interchangeable.
• What causes the magnet to fail to hold? This is often due to a weak thermocouple signal or carbon buildup. Ensure the thermocouple is generating at least 25-30mV under load before replacing the magnet head.
• Does this include the valve spring? Yes, this kit includes the replacement spring and diaphragm, which are essential for restoring proper mechanical tension within the safety valve.
