Take" API/ASME" as standard for designing and manufacturing or comply with IBR,CCE Certification. Boiler safety valve Information:A48/Y-100Itypeis used for power plant boilers, pressure containers, pressure and temperaturereducing devices and other facilities.Structure briefing1.Hangzhou brand safety valve is noted for elegant design, no leakage, setting pressure precision, greatly discharge and easily adjusted.2.Nozzle seat: It is the Loware nozzle type seat, the stem reaches the velocity of sound whenpassing the exit way of the seat, the sealing surface is welded by cobalt hard alloy with great corrosion resistance and long durability.3.Thermo elastic disc: the disc is of thermo elastic structure, taking the advantage of its flexibility to raise the sealingability, and solve the pre-discharge phenomenon effectively.the sealed surface of the disc has adopted the advanced technology of heat harding to increase thehardness and the ability of anti-friction and corrosion resistance.4.Adjusting nut: adjust the compression amount of spring by usingpet nut so that the valve canacquire appropriate set pressure rapidly andeasily.Installation instruction1. The safety valve shall be installed vertically and it would be better to install the valve directly upon the adaptor of the contcuner or pipe, the inside diameter of the adaptor shall be no less than that of the inlet pipe.2. To avoid the thermal stress which caused by the thermal expansion of the discharge pipe, the exit way of the safety valve shall be expansion with appropriate joint, the inside diameter of discharge pipe should large than the exit way of valve, and the pipe length shall be as short as possible and without bent.3. The exit way of the muffer shall have enough area, in order to avoid producing back pressure to affect the discharge ability of the valve.Basic information: Name of partA48Y-100IBodyZG20CrMoDisc holderWCBBonnetWCBCapWCBSeatCr12+stlDiscCr12+stlSpringAlloy StStemCr13Adjusting ringCr13Sealing surface of material"Y" representsDepositing stelliteAbove is the brief infromation,more details such as connecting information or dimensions pls contact us.
