A balanced valve element and a pressure regulating valve comprising the balanced valve element. The balanced valve element comprises: a valve rod (11), a piston sleeve (12) fixed on the valve rod (11), and a fixing member (14) sleeved between the valve rod (11) and the piston sleeve (12), wherein the fixing member (14) is disposed in a direction parallel to the axis of the valve rod (11). The fixing member (14) is connected to an actuator of a valve and the fixing member (14) is disposed between the valve rod (11) and the piston sleeve (12) in the axis direction of the valve rod (11), so that the valve rod (11) can be guided, and meanwhile a sealing effect of isolating the pressure at an inlet (21) and the pressure at an outlet (22) is achieved. |
