FIELD: controlling.
SUBSTANCE: group of inventions relates to a control assembly intended for use with various types of flow controllers. Control valve assembly comprises a collector with an internal flow network and flow controllers connected to the internal flow network for the passage of fluid between said controllers. The flow controllers comprise a control valve with a fixed setting, a first adjustable control valve, and an adjustable limiter. The outlet of the control valve with a fixed setting is connected to the inlet of the first adjustable control valve via the flow network. The outlet of the first adjustable control valve is connected to the adjustable limiter and to the ports on the collector via the flow network for the purpose of fluid communication.
EFFECT: more accurate control.
