American Thermowell offers both RTJ orifice plates, along with RTJ plate holder assemblies which include the required universal orifice plate.

RTJ Plate holders are a great solution for applications were frequent size changes or replacements are expected. Ring type joint orifice plates contain an intergral gasket that mounts between the ring tougue joint flanges. Plate thickness is calculated based on line size and pressure, this helps prevent the plate from possible failure.
