Introduction
Since 1941 the Inter-Service title "CV" has been used for names
of new valves instead of the previous individual Service type designations
(NR, AR, VR etc.). The system has now been extended to include all valves
used by the Services and this book is a complete register to the date
of issue.
The register is in two parts:
Part "A" contains mainly those valves newly introduced into
Service use where a functional description is necessary.
Part "B" contains those valves already in Service use or standardised
as more or less well known commercial types, where a functional description
is not necessary.
Governing specification: this column indicates the source of the specification
to which the valve is accepted by the Services:
AD = Admiralty (UK)
MOS = Ministry of Supply (UK)
MAP = Ministry of Aircraft Production (UK)
GPO = General Post Office (UK)
JAN = Joint Army-Navy Committee (USA)
COM = Commercial i.e. the current factorty test schedule of teh maker
concerned
IS = Inter-Service i.e. a specification common to two or more of the British
Services exists
