Electric valve is used for controlling the supply pressure to the units of automation, requiring prolonged exposure to the working environment.
When manufacturing and assembling of electric valves effective methods of quality control are used, such as: flaw and X-ray detection, magnaflux inspection, hydraulic and pneumatic testing, testing of air-helium mixture, etc.
