Trip & Throttle Valve Overhaul Frequency

Trip & Throttle Valve Overhaul Frequency

(OP)
I am looking for feedback from users on frequency of preventative overhaul of TTVs (Gimpel and others). Manufacturer recommendation is for overhaul on ~5yr interval, to ensure valve condition will allow function if required to trip machine. Are you performing overhaul on this interval?

RE: Trip & Throttle Valve Overhaul Frequency

yes , you can increase it to 6 or 7 years, this depends on the reliability and RCA of past failure.
