Description & Features
This unique cage has a series of diametrically opposed drilled holes that break the flow stream into many smaller streams. For liquid applications, the multi-hole trim is used as “flow into the cage”.
Thus the high velocity streams impinge upon each other which dissipates the energy and keeps the cavitating liquid away from metal valve parts. For gas/steam applications, the multi-hole trim is used as “flow out of the cage”.
Thus the high velocity streams radiate out of the cage causing a redistribution of the acoustical energy with resultant noise attenuation.
CV2800 control valve multi-hole cage designed single-stage, not only anti-cavitation damage and lower noise, but also provides easy maintenance and long life.
