The invention relates to a high-quality pressure control valve. The high-quality pressure control valve is characterized by comprising a control valve body (1), wherein the control valve body (1) comprises a valve body (2), and a valve rod (3) is connected to the valve body (2); an execution mechanism (4) is fixed at the tail end of the valve rod (3); the outer part of the part, exposed out of thevalve body (2), of the valve rod (3) is sleeved with a locking device (5), the locking device (5) is composed of a fixing block (6) and a locking rod (7), and the tail end of the locking rod (7) is in contact with the part, arranged in a longitudinal through hole (6.1), of the valve rod (3); and a flow monitor is arranged in a pipeline of the rear side of the valve body (2), and corrosion-resistant coatings coat the valve body (2) and the execution mechanism (4). According to the high-quality pressure control valve, when the valve needs to be repaired, as long as the valve rod is fixed through the locking rod, the va
