Description

Product Description

The WATTS 0274428 pressure relief valve is designed for hot water heating and domestic supply boiler applications. It protects against excessive pressures with its bronze body construction, FNPT connections, and non-metallic disc-to-metal seating. The valve resists corrosion, sticking, and freezing, preventing sediment from being trapped in the seat. Designed for emergency safety relief.

  • Seat located above drain prevents water and sediment from fouling the seat.
  • Non-mechanical seat-to-disc alignment prevents sticking or freezing.
  • Water seal isolates spring working parts from water during relief.

Product Highlights

This pressure relief valve is ideal for use in hot water heating and domestic water supply boiler applications.
