4 Introduction Explosion-Proof Valves Explosion-proof valves: now also available with IECEx-certified solenoids Parker has expanded the range of application for its explosion-proof industry hydraulic valves. ll series (exception: RE06M*W*EE) are not only EX certified but also equipped with IECEx compliant solenoids. Parker has certified the solenoids of these explosionproof directional control valves in accordance with IECEx standard for equipment class 2 G, as well ensuring EX compliance. echnically-speaking the new valves are practically unchanged. oth the performance characteristics and the dimensions are identical to the values of the previous versions, so that the valves can also easily be used as a replacement in existing systems. mong other things, the provided operating instructions contain: EC declaration of conformity for the valve Safety instructions Operating instructions, CE type examination certificate and declaration of conformity for the solenoids ll valves offered in this catalogue are EX certified for usage in zone 1 and 2, series RE06M*W*EE additionally for zones 21 and 22.

37 Characteristics Direct Operated Prop. Pressure Valve Series RE06M*W*EE Explosion Proof Pressure relief valves of the series RE06M*W*EE are direct operated proportional valves typically used as remote control valves for flow rates below 3 l/min. Function When the pressure in port P or exeeds the pressure setting at the solenoid, the cone opens to port and limits the pressure in port P to the adjusted level. he optimum performance can be achieved in combination with the digital amplifier module PCD (not explosion proof). he explosion proof class is II 2 GD c 130 C (4) for use in zones 1, 2, 21, and 22 (conform to EX). Features Direct operated with proportional solenoid Very low pressure adjustment of p min 2 pressure ports, and P (1 pressure port for XG087) Subplate mounting according to ISO pressure stages RE06M*W EE Standard RE06M*W EE XG087 RE06M*W*EE Standard RE06M*W*EE XG087 37
