      The double spring type safety valve is suitable for the equipment and pipeline of steam, water and other media with working temperature < 350 C. As an overpressure protection device.


      The materials of A38Y, A43H and A37H double spring relief valves are the same as those of A47H and A48Y spring relief valves except three-way (WCB).


      Type A38Y, A43H, and A37H double safety valves are constructed by installing two A48Y or A47H safety valves of the same specification on the Y-joint. The nominal diameter series refers to the inlet diameter of the Y-joint. The combination of these two safety valves is as follows:
