Peterson Instruments’ Orifice plates are made to the most rigorous of design specifications*. We stock 316 sst with other material available on request. Each plate has its heat number, bore, OD and material spec engraved and not hot stamped or acid etched to ensure this information on the outer edge is clear and legible for the lifetime of the plate.
