Orifice Plate Spools

Two designs of orifice spool

Two designs of orifice spool are available. The first is a square edge design where the face of the orifice has a flat profile. The second is a conical design that utilises a tapered profile to reduce the bore to the orifice size. The OP1 and OP2 designs are manufactured in 316L stainless steel with wetted surfaces finished to 0.5 microns Ra.
