eX D Flameproof
ASCO 314 solenoid Valves
ASCO 314 series are flameproof solenoid valves with a flameproof enclosure for use with applications in hazardous areas and potentially explosive atmospheres – in accordance with explosion protection concept type Ex d (Flameproof). They are direct operated, pad mounted solenoid valves with an aluminium body and can be used with an LPKF type valve operator.
These series of solenoid valves are manufactured and certified for hazardous area use according to ATEX, IECEx and IEC regulations.
The valves feature a 1/2″ NPT threaded entry hole, into which any IECEx or ATEX approved cable entry device can be fitted.
ASCO 314 series valves can be rotated 360°, allowing the user to select the best mounting position for cable entry to suit each individual application, without affecting operation.
