Is the D25403 kit compatible with older GP-2000 models?
Yes, the D25403 is the designated K-2110 pilot valve kit for all standard GP-2000 pressure reducing valves, including those originally using the discontinued 6020385 part number.

What are the symptoms of a failing pilot valve assembly?
Common signs include the inability of the main valve to reach the set-point pressure, erratic pressure fluctuations, or steam leaking from the pilot exhaust area, often indicating worn diaphragms or a fouled valve seat.

Does this kit include the main valve diaphragms?
No, this kit is specifically for the pilot assembly. It includes two pilot diaphragms and the pilot valve seat capsule. Main valve diaphragms must be purchased separately depending on the specific body size of your GP-2000.
