Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If solenoid or electric actuators
Electrically actuated valves use different statistical suffixes from purely thermostatic ones.
If basic steel fittings without control
Non-controlled pipe fittings revert to Chapter 73 steel articles.
If complete thermostat assembly
Standalone thermostats for any process are in Chapter 90 as automatic controls.
