The "Y" connection hose features a pressure regulation valve in order to control and adjust the suction or vacuum flow in each of the hose outlets. Its main function is to allow the professional to adjust the suction intensity in each of the cups connected to the "Y" hose. The regulation valve consists of a knob that can be turned to increase or decrease the suction flow in each hose outlet. By adjusting the knob, the negative pressure generated by the vacuum therapy equipment is controlled, thereby controlling the suction intensity in each cup.
