Electric single seat control valve by a pneumatic multi-spring diaphragm actuator and low flow resistance through single seat valve (sleeve valve) composed of electric valve, single seat valve body through single-seat cover guide structure, the valve plunger type structure, Compared with ordinary single-seat valve has a small size, light weight electric valve how much traffic and other characteristics suitable for 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. Electric shut-off valve advantages 1, simple structure, manufacture and maintenance more convenient. 2, the working stroke is small, open and close a short time. 3, sealing, friction between the sealing surface of small electric valve how to sell, longer life expectancy. 4, in the form of bellows globe valve body structure has a straight-through DC and right angle. Straight-through is the most common configuration, but resistance to its maximum fluid. DC-type fluid resistance is small, used for containing solid particles or viscosity of the fluid. Right Angle body to use more electric ball forging manufacturer, for smaller circulation, high pressure shut-off valve. 5, the opening and closing process than the valve sealing surface friction, wear. 6, usually only one sealing surface, the manufacturing process, and easy maintenance. 7, the electric actuator for easy operation.
