The DZW series of electric valve actuator is a 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 :Flame-proof type, global switch-type and
global regulation-type designs.
DZW series of products are used to control open and close of the valves. The products can be
used for brake valve, stop valve, shutoff valve, and diaphragm valve, the derived products can be
used for ball valve, butterfly valve and throttle etc., 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 flame-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: flame-proof type “d”), as well as JB/t8529-1997 (the technical conditions for flame-proof type
electric units).
1. Power supply: The motor is three-phase AC380V, 50 Hz. The control is two-phase AC 220V, 50
Hz, optional power supply: AC220~660V, 50.60Hz (needs to be explained during ordering).
2. Ambient temperature: -20~+60℃;optional temperature:-40~70℃.
3. Relative humidity: Not greater than 95% (at 25 ℃).
4. Working environment: The common type is used in the places without inflammable, explosive
and strong corrosive medium; the using environment of flame-proof products (ExdIIBT4) are
used in explosive gas mixture of IIA, IIB grades, T1-T4 groups.
5. Protective grade: IP65/67 (IP 68 for special ordering).
6. Working provisions for the motor: Rated operation time is 10min. Grade F insulation.
7. Anti-corrosive coating: High-temperature stoving varnish.
Notes:“I” indicates the connection dimensions of power station type product.
The parameters are used for common supplying, if you have special demands, please state during ordering.
The electric valve actuator includes 6 parts: Motor, reducer, control mechanism, manual-electric switching
mechanism, hand-wheel parts and electrical parts, the driving principle is as Figure I.
