Restriction Orifice Plate
Various type of Restriction orifice plate that depends on differential pressure is used as a simple pressure reducing device. Orifice calculations and design are according to the ISO- 5167 standard. Plate thickness which depends on line size and differential pressure should be strength enough to prevent the plate from bending under operating conditions.
RTJ plate holder will be supplied for the tags which their flange facing is RTJ.
In inconvenient condition when it is necessary to decrease the noise, multihole restriction orifice recommended.
