GENERAL CATALOGUE API

Solenoid operated valves, ATEX coils and connectors Complete solenoid operated valves type XA - XA1, intrinsic safety Ex ia

Main features Solenoid operated valves supplied complete and already mounted, composed by the desired valve body, 30 mm Ex ia intrinsic safety coil (voltage 21.6 ÷ 28 V DC) and relevant connector. The Ex ia coil (and its connector) can be matched with: - valve bodies series A1E size 1/8", 1/4" and 1/2", electric actuated, also with external air pilot; - valve bodies series A1NE size 1/4", electric actuated; - valve bodies series ISO size ISO1, with Cnomo or in-line pilot, and size ISO2 with Cnomo pilot, electric actuated, also with external air pilot. These solenoid valve are available in two different ATEX classification: Type XA is conforming to 2014/34/UE ATEX Directive suitable for applications in potentially explosive atmospheres, Group II, cat. 2 Gas & Powders, temperature class T6, protection grade IP65. Type XA1 is conforming to 2014/34/UE ATEX Directive for applications in potentially explosive atmospheres, Group II, cat. 2 Gas & Powders, temperature class T4, protection grade IP65. For code key see from page 2.321.2 For dimensions see from page 2.321.4 For further information on the ATEX 2014/34/EU Directive, on classifications and protections, see from page III.1
