Service Environment and Main Technical Parameters

1. Power Supply

Remote Control: DC 24V, minimum value for on of control signal gate is 20V, and maximum value for off is 1.5V; actuating current of control signal is 15 mA (approximate the load of 1.6kΩ, 0.36W)

2. Service Environment

1Flameproof type: according to the standard, these actuators are provided with Class dI (as electric apparatus for colliery mine) and Class dIIBT4 (for plant and works). Class dIIBT4 is suitable to the atmosphere of explosive gases mixture specified by groups T1~T4 of Class IIA and ClassIIB. Class dIICT4 is for special order (for details, see Std GB3836.12000 ELECTRICAL APPARTAS FOR EXPLOSIVE GAS ATMOSPHERESPART I: GENERAL REQUIREMENTS )

(2) Normal type: no corrosive, flammable or explosive media

(3) Ambient temperature: -20~60

(4) Relative humidity: ≤90% (at 25)

(5) Protection: IP55 (IP67 for special order). These actuators are for short time duty.The rated operating time is 10 minutes.

General Description

Integrated normal type and integrated explosion type multi-turn electric valve actuators consist of ZB5~ZB40, ZC45~250 and ZB5B~ZB40B, ZC45B~ZC250B electric valve actuators and additional electric control elements. And ZC350~ZC1000BZ actuators are combined with ZC180~250BZ actuators and additional gear reducers. With control module and big capacity contactors built in, these series electric valve actuators need no more electric control box. And so they are small in size and of complete functions (provided with automatic correction of phase sequence, protection of phase-lacking, four modes of remote control, and the function of emergent valve shut in addition), simple in installation and wiring (once the 3-phase power supply is connected, can local operation be carried out), easy to maintain and repair (electric circuit is controlled by DC 24V voltage, electric elements are connected one another with plugs and sockets).
