Analytical review of four-way directional valves used to control remote-controlled submarine valves

Today, in submarine projects, the largest group of actuators is remotely controlled valves, which are controlled by solenoid-controlled directional valves. Comparative analysis allows to select development options and evaluate alternative uses of devices to control remotely controlled valves. The article aims to conduct a comparative analysis of four-way solenoid-controlled directional valves used on submarines as control devices of remotely controlled valves. The comparative analysis shows that state-of-the-art directional valves have uniform design, specifications, and the operating principle, which are prerequisites for the development of a new, more compact and advanced directional valve to improve equipment layout in submarine compartments with numerous devices.
