Apollo Valve 10400 Series Bronze Safety Relief Valve ASME Hot Water 30 psi Set Pressure 34 NPT Female

This Apollo Valve 10400 series safety relief valve has a bronze body a 30 pounds per square inch psi relief pressure a 34 female National Pipe Thread NPT inlet connection and a 34 female NPT outlet The valves body and nozzle are bronze for resistant to corrosion the seat is EPDM ethylene propylene diene monomer for resistance to ozone and aging and the spring is stainless steel for resistance to corrosion The valve can be used in operating temperatures up to 250 degrees F This safety valve is American Society of Mechanical Engineers ASME safety rated for Section IV hot water heating boilers and hydronic heating systemsRelief valves remove excess pressure or vacuum from a system The valve openings allow fluids or gases to escape to decrease pressure and then close once the valve reaches the reseating pressure limit They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its lowpressure limit Some relief valves have an adjustment mechanism to set the pressure where the valve opens making it suitable for various applications Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas which may 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 generationApollo Valves manufactures ball mixing and relief valves actuators water gauges marine fittings heating and plumbing products and backflow prevention The company founded in 1928 and headquartered in Matthews NC meets international standard International Organization for Standardization ISOIEC standard 170252005
