Stainless steel soleids, ex-proof tex, IEEx or UL US, for hazardous areas -see section. Two executions are available: X stainless steel for external and internal parts, to withstand extreme and corrosive environmental conditions, and to ensure full compatibility also with water base and special fluids. XS stainless steel for external parts to withstand extreme and corrosive environmental conditions. Internal components are derived from standard valves. irectional valves are available in two basic versions: poppet type, 3-way leak free (suitable for accumulator systems) or spool type, 4-way on-off valves. Explosion proof soleids with: -TEX 94/9/E certification, protection mode Ex II 2G, Ex d II T6//T3, Ex t 21 IP67 -IEEx worldwide recognized safety certification, Ex d II T6//T3, Ex t 21 IP67 - UL US certification, according to UL 1002 and S 22.2 n 139-1982 class I Group & (Group II & II to NE 505-7) HX and LOHX valves conform to SIL 3 safety level (TÜV approved).

The reference ambient temperature is -40 +40 (+45 for X*6), for higher ambient temperature (-40 +70 ) the temperature class has to be degraded (option /7). For UL US certification the temperature class is related to the coil power 12W or 33 W (2) For UL US certification the temperature class corresponding to the coil power 12W is t reported in the nameplate marking. For coil power 33W the temperature class is. (3) Max pressure on T port = 110 bar (4) Optional electrohydraulic venting available on request. Valves are provided by HNR seals, which allow min ambient temperature down to -40 (max oil viscosity = 380 cst). The min ambient temperature for valves with /PE option (FPM seals) is -20 Max ambient temperature for valves without soleids is 70. internal parts for X execution + internal parts for XS execution + HX(S) ISI 630 ISI 316L ISI 316L, 420, 440, 430F arbon steel ISI 302 HNR (buna) FPM (viton) LOHX(S) LOKX(S) LOPX(S) LPX(S) RT-*X(S) HMPX(S) LIMMX(S) ISI 630 ISI 630 ISI 316L ISI 630 ISI 630 ISI 316L ISI 316L ISI 316L ISI 316L, 420, 440, 430F ISI 316L, 420, 440, 430F ISI 420 ISI 316L, 420, 630 ISI 316L, 420, 630 ISI 316L, 420, 630 arbon steel arbon steel arbon steel arbon steel arbon steel arbon steel ISI 302 ISI 302 ISI 302 ISI 302 ISI 302 ISI 302 HNR (buna) FPM (viton) HNR (buna) FPM (viton) HNR (buna) FPM (viton) HNR (buna) FPM (viton) HNR (buna) FPM (viton) HNR (buna) FPM (viton) S LIX ISI 316L ISI 630, ISI 420 - ISI 302 HNR (buna) FPM (viton) 220 2,5 40 (60 PE) 120 (150 PE) 40 400 spring 30 35 6 std seals 315 420 500 400 350 350 /PE E135
