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;
The valve can rapidly reseat after overpressure relief to reach satisfactory blowdown.
