**VFF50-0400 position status monitor for VFF butterfly valves with high pressure pneumatic actuators is available to be ordered separately or will be

assembled to the valve if ordered at the same time. It is compatible with any high pressure pneumatic actuators without pneumatic or electro-pneu­matic positioner (e.g. VFF...XR/XS, VFF...CR/CS, or VFF...ER/ES).
