1061512 Pressure Relief Valve for Hot Water 1 inch x 1-1/4 inch 60 YIS5_L9YYF65
This Apollo Valve 10-600 series hot water relief valve protects against excessive water pressure due to failure of controls to regulate BTU input. It has a bronze body, a 60 pounds per square inch (psi) relief pressure, and a 1 female National Pipe Thread (NPT) inlet connection and 1-1/4 female NPT outlet. The valves body and spring cage are bronze for resistance to corrosion. The seat is silicone for resistance to high temperatures and is elevated for draining water away from the seat area. The spring is steel for resistance to corrosion, and a fabric-reinforced, molded EPDM (ethylene propylene diene monomer) diaphragm isolates the spring from water at all times. The valve can be used in operating temperatures up to 250 degrees F. This relief valve is American Society of Mechanical Engineers (ASME) safety rated for Section IV heating boilers and is suitable for hot water heating boilers and hot water supply systems.Relief valves remove excess pressure or vacuum from a system.
