SOLENOID PROPORTIONAL FLOW CONTROL VALVE POPPET,
NORMALLY CLOSED, PRESSURE COMPENSATED
Overview
Symbol
Description
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%
