Design and manufacture standard: Design and manufacture standard:
Design standard: ASME VIII, API520
Structure length: API526
Inside nominal diameter: 1/2”-20”
Pressure range: 150LB-2500LB
Key feature:
Compact structure, beautiful appearance, precision casting, and smooth surface.
The valve seat is separable to the valve body for easy maintenance.
The umbrella-type disc holder works with valve seat adjusting ring for adjustment, which can effectively increase the lift force, so that the valve can be fully opened rapidly at a low overpressure to discharge media;
