IP68 Exid II Bt4 Explosion-Proof Electric Butterfly Valve
Product Description:
Explosion-Proof Electric Butterfly Valve/Exid II Bt4/IP68
Description:
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.
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 135ºC
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
