Features of ZZY Self-operated steam pressure regulator valve
No need additional energy, equipment cost is low, suitable for explosive environments. Structure is simple, maintenance workload is small; Setting point is adjustable and adjusting range is wide, easy to adjust the user within the set range; Diaphragm actuator detection precision is higher than air cylinder actuator, action is sensitive, than the cylinder is the structure of high precision detection, action sensitive; Valve pressure balancing mechanism is equipped in valve, which makes the control valve has the advantages of sensitive response, precise controlling and high allowable pressure difference.
