AAK Hydraulic Solenoid Proportional Valve Benchmarking HydraForce SP08-21

This Monday, we launched a solenoid proportional valve equivalent to HydraForce
standard part SP08-21.

The features of this solenoid proportional valve:

Continuous-duty rated coil.
Efficient wet-armature construction.
Optional waterproof E-Coils rated up to IP69K.
Industry common cavity.
Compact Size.

The function of this solenoid proportional valve:
A solenoid-operated, 2 port, normally open, poppet type proportional, screw in
hydraulic cartridge valve designed for low leakage in load-holding
applications. When de-engergized, the SP08-21 allows flow from 2 to 1. Flow
from 1 to 2 is severely restricted. When the valve is partially energized (see
performance curve) the valve begins to throttle flow from 2 to 1. When fully
energized, the valves poppet closes on the seat, blocking flow from 2 to 1. The
cartridge will allow 1 to 2 flow after overcoming the solenoid force.

AAK has received 5 inquiries for this solenoid proportional valve within only 3
months, from May to July 2023, with 3 customers placed trial orders. This
hydraulic solenoid proportional valve is not only widely used, but also has
multiple functions, especially its good performance. Although some China
hydraulic cartridge valve manufacturers can produce this hydraulic solenoid
proportional valve, and its functions may also be compared to HydraForce
standard part SP08-21, their solenoid proportional valve performance may be a
problem.

AAK hydraulic cartridge solenoid proportional valve 2 advantages:
1. Internal leakage: 5 drops/min, benchmarking against HydraForce
2. Its service life is 2 times that of its peers

Technical parameters of AAK E-SP08-21 Hydraulic Solenoid Proportional Cartridge
Valve:
Max. Operating Pressure: 207 bar (3000 psi)
Flow: See PRESSURE DROP VS. FLOW graph
Internal Leakage: 5 drops/min max. at 207 bar (3000 psi)
Operating Fluid Temperature: - 40 to 100 °C (with Standard Buna N seals)

The newly launched AAK E-SP08-21 solenoid valve, benchmarking HydraForce,
within 3 months, received 5 inquiries, and 3 customer trial orders. You can
also try it out.
