They are usually maintained by specialist firms that have the expertise and parts to refurbish the valves and special work benches with steam or air to set the valves to their proper pressure. Some firms do that in mobile vans that they take to sites of turnarounds.

dejrit,

RMW is refering to what is known as hydrosetting (at least that's what they call it in my area). The specialist firm uses specialized equipment to measure the set point of the valve and correct it if required.

This needs to be done online but at reduced pressure. We use 80% of operating pressure.

This should be done by a third party (specialist firm) for accountability/safety reasons.

Hope this helps,
