Product Description

A48Y-100 high temperature high pressure safety valve
      This valve is used for power plant boilers, pressure containers, pressure and temperature reducing devices and other facilities. And service as overpressure protection device.
 
Structure briefing
     The safety valve shall be installed vertically and it would be better to install the valve directly upon the adaptor of the container or the pipe. The inside diameter of the adaptor shall be no less than that of the inlet pipe of the softy valve.
      To avoid the thermal stress that is caused by the thermal expansion of the discharge pipe, the exit way of the safety valve shall be expansion with appropriate expansion joint.  The inside diameter of the discharge pipe should larger than the diameter of the exit way of the valve. Its length shall be as short as possible and no bent is allowed. The weight of both the discharge pipe and the expansion joint shall not be applied to the safety valve, and they shall be fastened upon the construction. The distance between both centerlines of the discharge pipe and the body shall be as short as possible. A water drainage pipe shall be installed separately for each safety valve.
     The exit way of the muffler shall have enough area, in order to avoid producing back pressure that would affect the discharge capability of the valve.
     A48Y-C for temperature <=425ºC; A48Y-V type is suitable for temperature <=550ºC Such as the boiler used in power station, pressure vessel, pressure reducing and temperature reducing device.  They are used as overpressure protection device.

     U-ideal Brand safety valve is noted for elegant design, No leakage, setting pressure precision, greatly discharge and easily adjusted.
Nozzle seat:  It is the Low are nozzle type seat.  The steam reaches the velocity of sound when passing the exit way of the seat. The sealing surface is welded by cobalt hard alloy, large displacement coefficient, anti-friction, corrosion resistance and long durability are recognized
Thermo elastic disc: the disc is of thermo elastic structure. Taking the advantage of its minor out-of -shape feature when under the  medium pressure,  the seal  ability has  been raised,  and the problem that pre -discharge phenomenon of the main safety happens when the medium pressure approaching the set pressure has been overcome. The sealed surface of the disc has adopted the advanced technology of heat hardening to increase the hardness and the ability of anti-friction and corrosion resistance.
     Adjusting nut:  adjust the compression amount of spring by suing pet nut so that the valve can acquire appropriate set pressure rapidly and easily.
      Back pressure adjusting sleeve:  it is an auxiliary apparatus that serves to adjust the back pressure of the disc to acquire appropriate differential pressure for seat returning.  If adjust upward, the back pressure of valve reduces. If adjust downward, the back pressure rises. 

     Types of safety valve: Pilot operated safety valve , Supplementary loaded safety valve, Assisted safety valve, Direct loaded safety valve, Controlled safety valve, Bellows safety valve, Diaphragm safety valve, Balanced safety relief valve, Pilot operated pressure relief valve and others.
