Product Details

The ZW, ZB series of 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 :Flame-proof type, global switch-type and global regulation-type designs.

ZW,ZB 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.

Note: 1, Such as user needs, the factory can ovide additional speed 12/18/24/30/36/42/48/60 (r/min).

2, The conventional supply by three rows of counters, such as when a large numbe of turns

orders indicate, acco ng to counter supply four rows.

Multi turn valve actuators, known as Z type. 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 of. They have a fullfeatured, reliable performance, advanced control systems, smallsize, light weight, easy to use and maintain. Widely used in electric power, metallurgy, petroleum, chemical, paper, desulphurizationand dust removal, sewage treatment and other industries. Multi turn electric actuators are: outdoor type, flameproof,the overall pattern,

the overall adjustment type, the overall type explosion, explosion overall adjustment type. By

connection type, is also divided intotorque and thrust.
