Typical characteristic of a normal

pressure or flow control valve or

variable piston pump Electro-

hydraulic stroker. This option will

NOT allow ‘fail-to-full-speed’ safety

operation.

It is strongly recommended that the

INVERTED option is used in

conjunction with a reverse operating

pressure control valve to allow

‘fail-to-full-speed’ operation.
