SYMBOL:HSPEC16-30 Valve symbol

 

DESCRIPTION
A high pressure, proportional, solenoid-operated, 3-way, normally-closed, flow control, screw-in
hydraulic cartridge valve intended for post-compensated applications with load-sense systems. In post-
compensated systems, the load-sense port 1 of the HSPEC16-30 valve is connected to the highest
load, which maintains flow sharing when flow demand exceeds flow supply. Pressure compensation
value of the valve defined as pressure difference between inlet and load sense ports is provided by
appropriate setup of a pump load sense control or by additional pressure compensator valve, one for
the whole system, in case the pump is non-adjustable.

OPERATION
When de-energized, the HSPEC16-30 blocks flow from port 3 to port 2. The valve will regulate flow out
of port 2 regardless of load pressure with flow rate proportional to current applied to the solenoid.

FEATURES
• Industry-common cavity.
• Continuous-duty rated coils.
• Reduced manifold space claim.
• Efficient wet-armature construction.
• Optional waterproof E-Coils rated up to IP69K.
• Flow sharing possible
• 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%
