The valve's body\r\nand nozzle are bronze for resistant to corrosion, the seat is EPDM (ethylene\r\npropylene diene monomer) for resistance to ozone and aging, and the spring is\r\nstainless steel for resistance to corrosion. The valve can be used in\r\noperating temperatures up to 250 degrees F. This safety valve is American\r\nSociety of Mechanical Engineers (ASME) safety rated for Section IV hot water\r\nheating boilers and hydronic heating systems.Relief valves remove excess\r\npressure or vacuum from a system. The valve openings allow fluids or gases to\r\nescape to decrease pressure, and then close once the valve reaches the\r\nreseating pressure limit. They also relieve excess vacuum by opening to\r\nrelease a gas into the system and then closing after it reaches its low-\r\npressure limit. Some relief valves have an adjustment mechanism to set the\r\npressure where the valve opens, making it suitable for various applications.\r\nRelief valves are rated according to the volume of liquid or gas that can flow\r\nthrough them and the material that the valve is constructed from must be\r\nsuitable for the fluid or gas, which may be corrosive or at an extreme\r\ntemperature, in which it operates. Relief valves are used in a variety of\r\napplications, such as air compressors, petrochemical and chemical\r\nmanufacturing, natural gas processing, and power generation.Apollo Valves\r\nmanufactures ball, mixing, and relief valves, actuators, water gauges, marine\r\nfittings, heating and plumbing products, and backflow prevention.
