Linear actuator for wedge / slide gate valves developed ( Extraction and processing of raw materials )

A linear actuator for wedge / slide gate valves has been developed. A two-stage gearbox converts the rotational motion of the engine into the translational motion of the rod without using a Bugel nut with low efficiency = 30%. The new structural solution allowed to significantly increase the efficiency of the valve with an actuator, which significantly reduced the engine power. The Du-300 gate valve with a pulling force of 15 tons on the stock is shown. The solution to the design of the linear drive is at the patenting stage. A prototype of such a solution was successfully implemented as a follow-up linear drive for a fire helicopter of the Ministry of Emergencies with an effort of 1.5 tons
