Temperature And Pressure Relief Valves

Watts 740 Series pressure relief valves are ideal for protecting water heating equipment from excessive pressure. They are used in the pipeline or with vessels in pneumatics applications. These valves feature an iron body ensuring structural rigidity and durability. They feature non-mechanical seat-to-disc alignment that prevents the valve from sticking or freezing, ensuring smooth and consistent operation over time. Their seat is strategically located above the drain, preventing water from being trapped and sediment from fouling the seats. They can operate at pressures ranging from 30 to 75 psi (2 to 5 bar), providing reliable performance.

Watts N240 Series automatic re-seating temperature and pressure relief valves provide reliable and automatic protection for hot water storage tanks and water heaters in commercial applications. These valves have tamper-resistant bonnet screws that prevent unauthorised adjustments or tampering. They feature an automatic reseating function that prevents excessive temperature or pressure buildup within the water heater or storage tank. These Watts N240 Series valves offer stainless steel thermostat tubes to prevent corrosion.
