Abstract
A balancing valve spool and a pressure regulating valve including the balancing valve spool. The balancing valve spool includes a valve rod having a first end and a second end. The valve rod defines a longitudinal axis that extends between the first end and the second end. The balancing valve spool also includes a piston sleeve fixed to the valve rod between the first end and the second end. The balancing spool valve further includes a fixing member arranged between the valve rod and the piston sleeve. The fixing member extends in a direction parallel to the longitudinal axis of the valve rod. Connecting the fixing piece to an actuator of the valve and arranging the fixing piece between the valve rod and the piston sleeve along the axial direction of the valve rod, guides the valve rod and simultaneously isolates inlet pressure and outlet pressure.
