DZW Electric Valve Actuator
The DZB,DZT series of electric valve actuators are new generation of products independently developed by our company by improving and perfecting structures, optimizing protective performance and key parts on original mature products, it has some advantages, such as: Compact structure, small volume, beautiful appearance and stable performance etc. The excellent protective grade can meet demands of many designs :Explosion-proof type, on-off type and modulating ype designs. DZB,DZT series of products are used to control open and close of the valves. The products can be used for gate valve, globe valve, shutoff valve, and diaphragm valve. The product can accurately act according to the control instruction, therefore it is necessary driving unit for achieving remote control, centralized control and automatic control. Performance of the product meets the provisions of JB/T8528-1997 (The technical conditions for electric units of common valves). The explosion-proof performance meets the requirements of GB3836.1-2000(the electrical equipment used for explosive gas atmosphere, Part 1: General requirements), GB3836.2-2000(the electrical equipment used for explosive gas atmosphere, Part 2: explosion-proof type "d"), as well as JB/t8529-1997 (the technical conditions for explosion-proof type electric units).

Manual-electric Mechanism
The manual-electric switching mechanism is a semi-automatic switching, the handle needs to be pulled to switch when manual, and it will run automatically when the manual state changes to electric. It consists of a handle, a switching piece, an upright rod, a clutch, a compression spring, etc. When handwheel operation is required, push the handle to the manual direction, and the switching piece will raise the clutch and compress the compression spring. When the handle is pushed to a certain position, the clutch will disengage from the worm wheel and engage with the hand wheel. At the same time, the upright rod stands upright on the end face of the worm wheel under the action of the torsion spring, supporting the clutch from falling. After the switching is completed, the handle can be released and the hand wheel can be used for operation. . When electric operation is required, the motor will drive the worm wheel to rotate, and the upright rod supported on the end face of the worm wheel will fall down. Under the action of the pressure spring, the clutch will quickly move to the direction of the worm wheel, mesh with the worm wheel, and disengage from the hand wheel at the same time, automatically realizing manual operation. transition to electric state.
Applications
Z series multi-turn electric actuators are suitable for opening and closing parts of the linear motion valves, such as gate valves, globe valves, diaphragm valves, gates,water valve etc. For the valve to open, close or regulation. Remote control valve is achieved,the essential drive control and automatic control. They have a full featured, reliable performance, advanced control systems, smallsize, light weight, easy to use and maintain. Widely used in electric power, metallurgy, petroleum, chemical, paper, desulphurization and dust removal, sewage treatment and other industries. Multi turn electric actuators are: outdoor type, explosion-proof,the overall modulating type, the overall type explosion, explosion overall modulating type. By connection type, is also divided intotorque and thrust.
