Robertshaw 1720-003 Valve Assembly R-410A pressure switches are calibrated toThe Robertshaw 1720 003 is a critical thermomagnetic safety valve engineered for precision fuel management in commercial and residential gas applications. As a TS11J series complete magnet and body assembly, this unit is designed to immediately terminate gas flow to both the pilot and main burner during a flame outage. The integrated safety magnet head assembly relies on millivoltage generated by a thermocouple; when the pilot flame is lost, the drop
