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

Main features Stainless steel 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: - stainless steel valve bodies series AX1E size 1/4" and 1/2", electric actuated, also with external air pilot; - stainless steel valve bodies series AX1NE size 1/4", electric actuated; These stainless steel 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 5.151.2 For dimensions see from page 5.151.3 For further information on the ATEX 2014/34/EU Directive, on classifications and protections, see from page III.1
