5.2 Lubricant information
Product owners and operating personnel select the Daniel Senior Orifice Fitting for use in a wide
variety of flow measurement services around the world. Information and experience gathered
indicate that measurement service conditions do have a profound effect on the metal-to-metal
slide valve sealing performance.
Each application presents its own unique set of service and environmental conditions.
Therefore, Daniel offers four lubricant greases for use on the grease assisted, metal-to-metal
Senior slide valve. These lubricants are:
The information contained in the following charts below are the result of sealing tests using a 3"
ANSI 600 Senior Orifice Fitting. Daniel performed these tests under various laboratory
conditions using nitrogen gas as the fluid. All sealing parts and grease were new. Test
technicians also cleaned the grease delivery system prior to every test. Each chart represents
one of the Daniel greases listed above.
In this test every filled grid indicates optimum seal performance at a corresponding
temperature and pressure coordinate. The criteria for determining optimum sealing
performance under test conditions was that, an electronic pressure transducer mounted on the
Top (14) detected no leakage across the slide valve thirty (30) minutes after grease insertion.
Every grid NOT filled indicates that some leakage occurred within the 30 minutes.
In order to perform a safe and efficient plate change operation, Daniel emphasizes that the on-
site operator evaluate both the service and environmental conditions prior to selecting a
lubricant. Additionally, Daniel realizes that some operators do allow leakage during a plate
change operation for metal to metal valve seats based upon their experience and the service
conditions under which they are operating and have performed successful and safe plate
changes.
One important factor for an owner or an operator to consider when selecting a grease for a
particular application is plate change time. This is the period in minutes required for an operator
to initiate, and complete, the Orifice Plate (13) change operation.

LEAKEAGE OF TOXIC FLUID HAZARD
For Seniors with a soft-seated valve and grease-assisted slide valves, do not use the “QUICK
CHANGE” procedure if the time to complete the plate removal and installation process will
exceed 15 minutes.
Exceeding this time frame can allow leakage of possible toxic fluid from the seal. Failure to follow
these instructions may result in serious injury or death.
