The VECTOR Series Pilot Valves are UL approved, direct mount (NAMUR VDI/VDE 3845) valves used to pilot pneumatic actuators. The valve is a universal type (5/2 convertible to 3/2) and can be easily field retrofitted for use on double acting or spring return actuators. The VECTOR-PV4 is a NEMA 4/4X Version. Also available in an [ATEX] Rated version for Hazardous Areas, VECTOR-PV7; and the Intrinsically Safe NAMUR Pilot Valve VECTOR-PV9. The VECTOR Series are fitted with a manual override function - helpful in the event that the valve must be cycled when electrical supply is unavailable.
