Featuring a robust \u003cstrong\u003ebronze body\u003c\/strong\u003e and a \u003cstrong\u003e1-inch NPT female inlet\/outlet\u003c\/strong\u003e, this valve is engineered to manage extreme thermal and overpressure conditions. It provides a massive \u003cstrong\u003e4,059,000 BTU\/hr\u003c\/strong\u003e steam discharge capacity at a \u003cstrong\u003e150 psi pressure relief\u003c\/strong\u003e setpoint, alongside a \u003cstrong\u003e210°F temperature relief\u003c\/strong\u003e setting. The 9-inch \u003cstrong\u003estainless steel extension thermostat\u003c\/strong\u003e ensures accurate thermal sensing deep within the tank for reliable performance. This model comes integrated with \u003cstrong\u003eSentryPlus Alert technology\u003c\/strong\u003e, featuring a flood sensor on the discharge line to detect excessive water discharge before it leads to facility damage. When utilized with a compatible activation kit, it allows for proactive monitoring through building management systems, making it an essential component for critical plumbing and HVAC infrastructure where flood mitigation is a priority.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh BTU Capacity:\u003c\/strong\u003e Rated for \u003cstrong\u003e4,059,000 BTU\/hr\u003c\/strong\u003e, providing maximum safety for high-output commercial water heating systems.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSentryPlus Alert Technology:\u003c\/strong\u003e Built-in flood sensor helps prevent catastrophic water damage by detecting and signaling relief valve discharge.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDurable Bronze Construction:\u003c\/strong\u003e Features a corrosion-resistant bronze body with \u003cstrong\u003etamper-resistant bonnet screws\u003c\/strong\u003e to ensure system integrity in demanding environments.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDual Protection:\u003c\/strong\u003e Combines reliable \u003cstrong\u003e150 psi pressure relief\u003c\/strong\u003e and \u003cstrong\u003e210°F temperature relief\u003c\/strong\u003e in a single, standard-sized 1-inch assembly.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomatic Reseating:\u003c\/strong\u003e Precision-engineered for non-mechanical seat-to-disc alignment, allowing the valve to close securely once pressure returns to safe levels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this valve require an external kit for the flood sensor to work?\u003c\/strong\u003e\u003cbr\u003e\nYes, while the \u003cstrong\u003eWatts N240X-9\u003c\/strong\u003e includes the SentryPlus sensor hardware, you must purchase a separate activation kit (BMS or Cellular) to connect the sensor to your building management or notification network.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan the 9-inch thermostat probe be cut or shortened for smaller tanks?\u003c\/strong\u003e\u003cbr\u003e\nNo, the \u003cstrong\u003estainless steel thermostat\u003c\/strong\u003e probe should never be modified.
