Description / Abstract:

This standard specifies methods of testing for rating flow and pressure characteristics of solenoid valves intended for continuous duty service using liquid as a test fluid, including the valve flow coefficient (Cv/Kv) for comparison of valve capacity.

This standard is not applicable to hydraulic fluid power valves, for which different methods of test and rating, presented in standards developed by NFPA and ISO/TC 131, are accepted and used throughout the fluid power industry.


The purposes of this standard are to:

List and define the terms and abbreviations used in testing.

Specify the data required.

Specify the methods of test for obtaining capacity ratings of solenoid valves.

Specify the method of test for obtaining the maximum operating pressure differential (MOPD) of solenoid valves.

It is not the purpose of this standard to provide the type of tests used for production or field testing, but to establish procedures for laboratory testing of valves.
