6.  Leakage across seat.

Possible Causes

Remedies

A. 

Contamination (debris) in regulator.

A. 

Remove internals, clean, and if necessary, replace sealing and seat-

ing elements.  *

B. 

Oversized regulator; valve plug operates

         directly next to seat.

B. 

Check actual flow conditions; resize regulator for minimum and maxi-

         mum flow; if necessary, replace with smaller regulator.

* Seat leakage may be diagnosed when a failure of the dynamic side seal has occurred. Inspect both potential internal leak paths.
