n Line Valve Chokes can be supplied with or retrofitted with a range of rotary
stepping actuators using either
compressed air, instrument gas or hydraulic
fluid for motive power.
The actuator is generally controlled vi a pulses to solenoid valves Position
is shown visually and also generally
transmitted from the actuator. Limit switches are also
commonly used to limit and indicate the end of travel.
Manual override can be via declutchable handwheel or a
hexagonal drive which will take a standard socket wrench
