1 Table TE137-1/E Stainless steel valves for water base fluids standard or ex-proof solenoid valves with Multicertification TEX, IECEx, EC or CULUS certification Ex-proof solenoid Valve body Solenoid plunger Spool / poppet Spring Manual override pin Cable entrance Standard solenoid DHXW4-07*/M DHOXW-* New line of directional solenoid valves with stainless steel internal parts for application with water base fluids. Features: These valves are made by selected inoxidizable materials for internal parts to withstand applications with water base fluids or just pure water. External components are derived from standard valves. Two basic versions are available, poppet type, 3-way leak free (suitable for accumulator systems) or spool type, 4- way on-off valves. The valves are available with standard or ex-proof solenoids, these last certified according to: - Multicertification TEX, IECEx, EC - CULUS certification ISO standard subplate mounting. Options for ex-proof version: Handwheel manual override (option /V) Manual reset (option /R) for safety applications Horizontal cable entrance. Common pplications: Steel plants, die casting, foundry. 1 STINLESS STEEL VLVES: MIN DT Code (1) DHOXW DLOHXW DLOHMXW DLOPXW DHXW6 DHXW4 DLHXW6 DLHXW4 DLHMXW6 DLHMXW4 DLPXW6 Voltages Multicertification Description ISO size DC C T class (2) Input 50/60Hz Standard Option /7 Power 4 way, spool type piloted solenoid valve 4 way, spool type piloted solenoid valve no no T6 T6 T6 T6 32 W (only for and 24 DC) 40 W (only for 110 and 220 DC) 8 W 25 W 8 W 25 W 8W 25 W 8 W T class (2) T6, T5 T6, T5 T6, T5 T6, T5 CULUS Input Power W 33 W W 33 W W 33 W W Max flow l/min Dp Max pressure (at max flow) bar (3) bar see diagram at section Notes: 1) XW6 and XW4 versions differ only for the coil power (see Input Power) 2) Solenoid temperature class, see section 3 3) Max pressure on T port = 110 bar Valves are provided by HNR seals, which allow min ambient temperature down to -40 C (max oil viscosity = 380 cst).
