摘要:
A valve body and a control valve including such a valve body, the valve body including an inlet, an outlet, a valve port defined therebetween, and a plurality of discrete flow channels extending between the inlet and the valve port to distribute fluid flow to the valve port in a manner that equalizes the velocity of fluid at the perimeter of the valve port. The plurality of discrete flow channels includes (i) one or more first flow channels arranged to direct a first amount of the fluid flow to a front portion of the valve port, (ii) one or more second flow channels arranged to direct a second amount of the fluid flow to a rear portion of the valve port, and (iii) one or more third flow channels arranged to direct a third amount of the fluid flow to one or both side portions of the valve port.
