SOLENOID PROPORTIONAL FLOW CONTROL VALVE POPPET, NORMALLY CLOSED, PRESSURE COMPENSATED The hspec12-34xx is a high pressure, proportional solenoid-operated, poppet type, restrictive type, pressure compensated, normally closed flow control, screw-in hydraulic cartridge valve with built-in damping and load holding features. Operation With inlet at port 3 the valve will regulate flow out of port 2 regardless of load pressure with flow rate proportional to current applied to the solenoid. Port 1 must be connected to port 3 to provide load sense function for the compensator. When de-energized, the valve blocks flow from port 3 to port 2 while allowing free flow in opposite direction. Features Industry-common cavity. Continuous-duty rated coils. Reduced manifold space claim. Efficient wet-armature construction. Optional waterproof E-Coils rated up to IP69K. Patented high-strength solenoid tube All HyPerformance™ valves are tested to the rigorous standards of NFPA specification T2.6.1 and are tested at a verification level of 90% and an assurance of 99% Fluids: Mineral based or synthetic hydraulic fluid with lubricating properties Fluid Viscosity Range: 7.4 to 420 cSt Maximum Operating Contamination Level: 18/16/13 per ISO 4406 Unit Weight: 0.32 kg (0.70 lb) Without coil and nut HSPEC12-34 HSPEC12-34A 0.33 kg (0.72 lb) HSPEC12-34T hspec12-34at Internal Wetted Surface Area: 313.4 cm² (48.57 in²) HSPEC12-34, HSPEC12-34A 317.8 cm² (49.26 in²) Hspec12-34t, hspec12-34at Note: With size 10 e-series coil Maximum Control Current: 1300 mA Coil 12 V 650 mA Coil 24 V Threshold Current: 200 to 550 mA Coil 12 V 100 to 275 mA Coil 24 V Dither PWM Frequency: 100 to 200 Hz
