Paint Color for Fail Safe Type Control Valve Actuator

12/26/2012 1:55 AM

We all know that there are three different fail safe (FO, FC & FL) actuators used with control valve depending on process requirements. So, I need your opinion for my following queries.

  1. Is it necessary to have different valve actuator paint color based on fail safe condition?
  2. If it required, then let me know the purpose of different paint color and the specific standards or guideline or client requirements for the same.

Thanks in Advance

The valve should be the same color as the pipe.

Provided the valve has been set-up as required, the set-up agrees with the as-built P&ID, there is a reliable test record and the P&ID has passed through a HazOp Study, the colour of the paint will make no difference whatsoever.
