Identify a valve

Enter the clues you know. Start with just one and add more to narrow down the candidates.

This page is under development. Results are possible matches and do not establish identity or electrical interchangeability.

In clue-based searches, you can separate characters with spaces. Original designations and verified aliases remain distinct.

Dimensions and weight

Choose what the measurement describes. Dimensions with unknown inclusions need checking and are not treated as overall height or height excluding pins.

Base, contacts and electrical data

Only verified mechanical families are used. Base positions do not describe electrical contact functions. Missing pins and top contacts need a separate comparison.

Enter only known data: do not power an unknown valve to identify it. Resistance alone does not reliably establish the rated voltage.
