FIELD: pipeline engineering.
SUBSTANCE: electropneumatic control device comprises explosion-protection chamber, electromagnets, air-operated valves whose inlets are connected with the source of compressed fluid and outlets are connected with the outlet passages through the controllers of the fluid flow rate, electromagnets movably connected with the air-operated valves, magnetically-controlled end switches, and permanent magnets connected with the inlet roll of the device. The control units of the flow rate controllers are movably connected with the inlet roll of the device. The electropneumatic device also has device for locking the levers of the local control of the air-operated valves.
EFFECT: enhanced reliability.
