ASCO WBLP SOLENOID OPERATORS

EX E MB INCREASED SAFETY & ENCAPSULATED

ASCO WBLP Operators are part of the explosion proof solenoid valve range manufactured by ASCO – the solenoid operators with Increased Safety and Encapsulation IEC explosion protection techniques. They are suitable for use in hazardous areas with exposure to gas, classified as Zone 1.

Hazardous Area Classification & Ex Safety Code

II 2G Ex e mb IIC T4 Gb
II 2D Ex tb IIIC T 135°C Db IP67

The Ex e mb solenoid operators used in conjunction with valves are compliant with International and European Standards EN-IEC 60079-0, EN-IEC 60079-7, EN-IEC 60079-18 and EN-IEC 60079-31 and also certified for use in potentially explosive atmospheres according to ATEX-Directive 2014/34/EU.

ASco wblp operators – features

• Ingress Protection Rating: IP67
• The solenoid operators have a moulded enclosure which features integral strain relief for cable with an O.D. of 7 to 8.5 mm
• ASCO WBLP are easily installed with a screw terminal coil
• Peak voltage suppression is standard for DC executions
• The coil winding is fitted with a thermal fuse (in AC/DC) which, in the case of excessive temperature due to prolonged over-voltage or a blocked core, will trip and cause the valve to de-energise and fail-safe
• A range of solenoid valves can be supplied with the Ex e mb operator
