Daniel Senior Model 2000 Orifice Fitting extends the proven technologies of the original Senior Orifice Fitting to include new features for improved safety, maintenance, and up-time while meeting all applicable API 14.3, AGA 3 and ISO 5167 specifications.

Maintenance and safety advantages of the Daniel Senior Model 2000 Orifice Fitting are realized by a new greaseless isolation valve that ensures sealing integrity. Regular maintenance visits for valve lubrication are eliminated with this design, as well as potential personnel exposure to content in the pipeline. Further, a redundant seal mechanism is incorporated to ensure continuous long-term operation.

Daniel Senior Model 2000 increases operation up-time and further reduces maintenance by use of a plate release mechanism that assists in removing a stuck plate carrier from the metering position. The design also incorporates standard o-rings throughout, allowing for reusability and longer life.
