1、The velocity of fluid with big pressure difference makes serious erosion to valve parts and lots of noise. The multi-hole cage of GC210 has well solved this problem. porous sleeve type well solves the problem. For a fluid flow from up to down, the velocity is reduced when the flow colliding in the multi-hole cage and flow energy is reduced. For a gas flow from down to up, there is a volume expansion when the gas goes through the multi-hole cage, then this would reduce the gas pressure and the velocity would be reduced.
2、The multi-hole cage of GC210 and the standard cage are interchangeable, and the other valve parts are in common use. This can optimize the resource, reduce inventory and shorten delivery time.
