ELECTROPNEUMATIC CONTROLLER

摘要

The invention relates to automatic appliances and aggregates and can be used in gas systems of various branches of engineering. An electropneumatic controller comprises a body with passages for working medium delivery and discharge. In the body a butterfly valve is provided with pneumatic drive interacting with a command unit. The last one has two pulse-control electromagnetic valves operating in a frequency mode. One electromagnetic valve installed on the working medium discharge to environment is normally open and closes at control mode switching. The technical result is in enhancement of performance reliability.
