    Hydraulic or pneumatic single-acting spring return operated actuators should be used for shut-down valves.

    Double-acting actuators may be used when this proves beneficial based on evaluation including weight, space, and price.

    Hydraulic actuators should be used.

    Hydraulic accumulators shall be of the piston type, nitrogen-charged, with piston position detection possibility.

    The valve control accumulator units shall be installed close to the valve.
