Category: Electric Actuator
Product name: Multi-turn Explosion-proof Electric Actuator
Model: Multiple turns
Product profile:
Multi-turn explosion-proof electric actuators is the latest innovation of light miniaturization explosion-proof actuators. Explosion-proof electric actuator product level Exd Ⅱ BT4 protective IP68 machine shell with maximum 25 turns.The products are exquisite and unique in appearance small in size light in weight and stable and reliable in performance.It is the ideal choice of small and medium caliber gate valve ball valve diaphragm valve plug valve and other electric matching.

Design features:
*All electrical and mechanical components are sealed in aluminum alloy shell with high instant explosion resistance pressure of 1.6MPa isolating the ignition source effectively.

*With "o "ring seal up to protection grade IP68 Each explosion-proof surface adopts circular clearance and CNC precision machining to achieve stable and reliable explosion-proof performance
*Output 0-24 turns by 0-360° worm wheel

*Stem Direct-Connected refer to IS05211

*Powered by 1-phase 3-phase or DC power supplies

*Bus communication Analog signal are available for your choice

*Permanently lubricated and maintenance free drive train

*Optional torque limiter/remote control

PRODUCT CHARACTERISTICS

Explosion-proof grade:
TA: explosion-proof series products of explosion-proof level for Exd Ⅱ BT4
The Ex
D:  Explosion-proof type: Explosion-proof
Ⅱ: Electrical equipment used in explosive gas environment  except the coal mine of device
B:  Explosion level:  the size (width and clearance) of the explosion-proof surface in accordance with the explosion level
T4: Temperature group: the maximum temperature in surface  is 135℃
In appendix B of GB3836.1-2000 the grade and temperature of combustible gas are listed in detail

[NOTED] the types and groups of explosive media around the place where the product is used must be consistent with those permitted by the product.Otherwise it can't play the explosion-proof effect in non-applicable environment
