SYMBOL:HSPEC10-34 Valve symbol

 

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.

OPERATION
With inlet at port 3, the HSPEC10-34 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, allowing free flow in opposite direction.

FEATURES
• Sealed integral compensator.
• Continuous-duty rated coils.
• Optional manual override.
• Optional waterproof E-Coils rated up to IP69K.
• 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%.
