This Apollo Valve 10-600 series warm water relief valve secures versus extreme water pressure due to failure of controls to manage BTU input. It has a bronze body, a 50 pounds per square inch (psi) relief pressure, and a 3/4" female National Pipe Thread (NPT) inlet connection and 3/4" female NPT outlet. The valve's body and spring cage are bronze for resistance to corrosion. The seat is silicone for resistance to heats and is elevated for draining pipes water far from the seat location. 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 temperature levels approximately 250 degrees F. This relief valve is American Society of Mechanical Engineers (ASME) security ranked for Section IV heating boilers and is appropriate for warm water heating boilers and warm water supply systems.Relief valves remove

excess pressure or vacuum from a system. The valve openings enable fluids or gases to get away to decrease pressure, and then close once the valve reaches the reseating pressure limitation. They likewise ease excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limitation. Some relief valves have a change system to set the pressure where the valve opens, making it appropriate for numerous applications. Relief valves are ranked according to the volume of liquid or gas that can flow through them and the product that the valve is constructed from must be appropriate for the fluid or gas, which might be corrosive or at an extreme temperature, in which it operates. Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation.Apollo Valves manufactures ball, mixing, and relief valves, actuators, water determines, marine fittings, heating and pipes items, and backflow prevention. The company, founded in 1928 and headquartered in Matthews, NC, meets worldwide standard International Organization for Standardization(ISO)/ IEC standard 17025:2005.
