Watts 0121571 Valve

The Watts 0121571 (Model LF174A-125) is a heavy-duty, 2-inch ASME water relief valve designed specifically for large-scale hot water heating boiler systems. This lead-free safety relief valve features a rugged bronze body and a 125 psi factory set point, delivering a massive discharge capacity of 12,170,000 BTU/hr. Engineered for high-capacity pressure relief, it utilizes a stainless steel spring and a non-mechanical seat-to-disc alignment to prevent sticking or freezing in demanding hydronic environments. The LF174A 2 inch configuration includes female NPT threaded connections, ensuring a secure fit for commercial boiler protection. As a veteran-grade ASME Section IV component, this valve provides critical emergency overpressure protection, maintaining system integrity even during process upsets. Its lead-free copper silicon alloy construction ensures compliance with modern safety standards while resisting corrosive water conditions and sediment buildup.

Key Benefits

  • Extreme Capacity: Rated for 12,170,000 BTU/hr to handle massive commercial heating loads.
  • Lead-Free Construction: Fabricated with a lead-free bronze body for durability and code compliance.
  • Reliable Operation: Features a stainless steel spring and soft-seated design to prevent seat fouling.
  • Industry Certified: Fully ASME Section IV certified for emergency water pressure relief.
  • Field Tested: Equipped with a standard test lever for manual override and performance verification.
