Antistatic device pertaining to bronze ball valves

Antistatic device pertaining to bronze ball valves

I would like some help pertaining to why or (and) why not anti-static devices are required on bronze ball valves.

RE: Antistatic device pertaining to bronze ball valves

Normally, trunion type ball valves with non-metallic sealings need anti-static device. This is to ensure static charges (which accumulate on the ball) being discharged through metallic connection to the ball via anti-static system.
For better understanding, see "valve selection handbook" by Peter Smith.

Hi McDermott1711,
Thanks for the response. I also did go to the referred literature and got the clarification I needed.
