Based on long-standing designing experience, Yuzhnoye SDO developed various automatic units for regulation of operation of Yuzhnoye-SDO-developed  engines and propulsion systems.:

• gas distributors;
• throttles (hydraulic, high-temperature, two-mode of cam type);
• valves  (shut-off, safety, diaphragm, stop, check, electric, electrohydraulic, pyro and electric pyro valves);
• switches;
• regulators (of pressure, pressure drop, fuel flow rate);
• pressure drop stabilizers.

Taking into consideration that the main purpose of the valves and regulating devices consists in regulation of operation of an engine or a propulsion system in different operation phases, the necessity arises of thorough elaboration of these actuators of launch vehicle and spacecraft flight control.

The experienced gained in designing and proved technology allow developing analogous units with wide range of characteristics and high operational reliability.
