Control equipment for use in hazardous areas must be carefully selected to meet area classifications.
SVF Flow Controls, through our NexTek Controls family of valve automation products, offers the right selection of actuators and controls for hazardous areas.
Standards of compliance include NEMA, ATEX, NEC and International Electrotechnical Commission (IEC)
The Top 5 products we supply are detailed below. Note that pneumatic actuators are included since they are commonly chosen for use in hazardous areas since they are inherently safe.
E Series • NEXUS-LPX • NEXUS-LX • PV7 • Pneumatic Actuators |

Mechanical switches are rated for temperatures from-15°F to 176°F (-26°C to +80°C)
Double acting or spring return actuators
Dual 3/4” NPT conduit entries facilitate wiring in the field and for additional ancillary pilot valve connections
Captive cover bolts remain intact during wiring to prevent loss
PV7
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-PV7 is [ATEX] Rated version for Hazardous Areas.
Also available in a NEMA 4/4X Version VECTOR-PV4 and the Intrinsically Safe NAMUR Pilot Valve VECTOR-PV9.
Fitted with a manual override function – helpful in the event that the valve must be cycled when electrical supply is unavailable.
