Product Name : Explosion-proof Electric Butterfly Valve

Product introduction:

Explosion-proof Electric Butterfly Valve has the non-pin structure to effectively avoid the pin break off in a long- term operation as a modulation device to control and cut off the various industrial medium of water and oil to realize temperature pressure and flow control.
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
This valve is suited to the pipeline and container of non corrosive gas liquid semi-liquid and solid powder and applied in the industrial fields of petroleum chemical food medicine textile papermaking power shipwater and drainage smelting energy and so on.

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
