Faedah dan Kelebihan Utama
-
Accuracy of Control: The large diaphragm area provides extremely sensitive pressure control, ensuring the tank pressure is maintained within inches of water column, even at very low setpoints.
-
Insensitive to Inlet Pressure Fluctuations: The balanced trim design ensures that variations in the supply pressure do not affect the regulated outlet pressure, providing a stable blanket.
-
Fast Speed of Response: The direct-operated design reacts instantly to changes in tank pressure caused by liquid pump-out or thermal contraction, preventing vacuum damage.
-
High Flow Capacities: Despite its precision at low pressures, the Y693 is capable of handling high flow rates to protect large tanks during rapid draw-down.
-
Balanced Trim Design: This feature allows for the use of higher inlet pressures while maintaining excellent control sensitivity and reducing seat wear.
-
In-Line Inspection and Maintenance: The top-entry design allows for quick inspection and replacement of internal parts without removing the regulator body from the pipeline, significantly reducing downtime.
Hartanah Teknikal
-
Operation: Direct-operated pressure reducing regulator.
-
Setpoint Range: Capable of controlling pressures as low as 0.5 inches w.c. (1.2 mbar).
-
Material Options: Available in cast iron, steel, or stainless steel bodies to accommodate diverse chemical environments.
-
