Parri cage guided control valve adopts cage balanced guide structure, and a pressure relief hole is set on the top of the cage, and a balance sealing ring is added to prevent the leakage of the back seat, which greatly improves the leakage class and is applied to working conditions with high leakage requirements. At the same time, it has a balanced trim that meets the working condition with high pressure differential. This series of control valves are suitable for wide range of applications and has excellent performance. It is one of the most commonly used control valves in industrial fluid control.
