Description
The HSPEC10-34X 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.
Note: Do not use an orifice disc wth this product.
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 HyPerformanceâ„¢ 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%
