Electric cutoff valve works electric valve, also known as electric sectional door, is the most widely used of a valve, the electric valve is a difference, it is the reason why the popularity is due to the process of opening and closing between the sealing surface friction force small valve manufacturer, more durable, opening height is not, how much easier to manufacture gate valve, easy maintenance, not only for the low-pressure valve parameters, but also suitable for high pressure. Electric shut-off valve is closed principle is to rely on electric thrust of the rotary valve lever valve, the valve disc sealing surface and seat sealing surface snug fit to prevent the media circulation. Electric shut-off valve can only medium-way flow, directional installation. Structural length is greater than the cut-off valve gate, while the fluid resistance, long-term operation, the sealing reliability is not strong. Electric single seat control valve by a pneumatic multi-spring diaphragm actuator and low flow resistance through single seat valve (sleeve valve), with single-seat valve body through single-seat cover guide structure, the valve plunger-type structure, with common Single-seat valve compared with small size, light weight, and other characteristics suitable for traffic flow, leakage demanding applications. ZJHM type fine small single-seat pneumatic control valve sleeve compared with ordinary sleeve valve, with a small volume of 1/3, 1/3 light weight, large 1/3 flow characteristics, widely used that require low noise, large pressure difference industrial process control systems.
