HydraForce, Inc. Proportional Flow Control Vave HSPEC12-34

DESCRIPTION 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 intended for use in gravity-lowering circuits. OPERATION With inlet at port 3, the HSPEC12-34 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 the 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 verfication level of 90% and an assurance of 99% RATINGS Operating Pressure: 350 bar (5075 psi); 10% cycle life; 420 bar (6090 psi) Note: All HyPerformance™ products are tested for 900K cycles at 350 bar and 100K at 420 bar. Proof Pressure: 690 bar (10000 psi) Burst Pressure: 1241 bar (18000 psi) Flow: 60 lpm (16 gpm) Internal Leakage: Port 3 to port 2: 8 drops/minute with 350 bar (5075 psi) at port 3 Temperature: -54° to 107°C (-65° to 225° F) with urethane seals Electrical Parameters (with size 10 E-Series coil): Coil Voltage Threshold Current Max.
