There
are two main configuration:
- SCM
Mounted: These are
remotely adjusted by pulsing electro-hydraulic
pilot valves. The flow rate through the
valve is measured by means of a differential
pressure sensor across an orifice.
- Externally
Mounted: These are adjusted by an ROV torque tool
and features a position indicator for a given flow.
This can be configured to fit on a stabplate to
allow ROV installation and retrieval.
