ATEX explosionproof circuit

ATEX explosionproof circuit

ATEX explosionproof circuit

(OP)
I am wiring a couple of ASCO Explosion Proof (ATEX  EExd IIC IP67) solenoid valves. Two valves are mounted so the conduit connections are on a tee, with the third leg of the tee connecting into an explosionproof switchbox on a ball valve actuator.  

My question is: Do I need to use sealed cable glands on all three legs of the tee? Or is one cable gland on the connection to the limit switch assembly code-compliant?

 

 

RE: ATEX explosionproof circuit

If it is in gas group IIC it requires a barrier gland.

If it is in Zone 1 with gas group IIA or IIB AND has an internal volume greater than 2 litres then it requires a barrier gland.

Otherwise a suitable flameproof gland with a sealing ring can be used.

Refer to EEMUA Publication 186 for some guidance - a useful document to have.
