Seated valve 500 Type WVM-4B NG 4 up to 12 l/min

Transcription

1 Seated valve 500 Type WVM-4B Features Direct operated Leakage free Good resistance to corrosion As 2/2-, 3/2-, 3/3-, 4/2-* or 4/3-valve with solenoid or alternative actuation * pilot-operated Design With hardened closing elements as cone or ball seat Functions with negative overlap Solenoids with slide on coil technology Mounting on single subplate (EAP) as stand-alone valve or in valve bank with supplate (APH) Applications Controlling of cylinders and motors in higher pressure ranges as full replacement for spool valve technology (especially for leakage free holding, bending and clamping) In machine tools, hoisting technology, test stands and rescue devices Power units (e.g. as with limited space conditions or weight reduction) Technical data Hydraulic fluid Fluid temperature range -20 to 80 C Ambient temperature range -30 to 50 C Viscosity range 5 to 400 mm 2 /s Porting Mineral oil according to DIN (other fluids on request) Max. operating pressure 500 bar continuous pressure (S1) / Higher pressures up to 700 bar temporary allowed! Pressure difference from P to A, B to T must be adhered! (p p > p A p B > p T) / 4/3-way valve p Tmax = 350 bar Duty cycle DC 100% (at continuous pressure operation) For higher pressures see characteristic hydraulic switching power Max. flow rate 12 l/min Filtration According NAS 1638 class 6 resp. ISO/DIN /15/12 DIN connector (2P + E) According EN / ISO 4400 / DIN Power Solenoid: 24 VDC (23 W) / 110 VAC (25 W) / 230 VAC (25 W) Power tolerance +/- 10% Switching time ms Degree of protection according DIN IP 63 (solenoid IP 65) Material Corrosion-resistant steel and aluminium (coil housing: ZnFe - corrosion protection)
