Pilot operated pressure relief valve
Sterling Hydraulics
SOLENOID ACTUATED Two functions in one valve, unloading and relieving. Factory set relief pressure or adjustable option. Integral 250 micron pilot flow filter. Coil: Waterproof, hermetically sealed, requires no O’Rings;
Symmetrical coil can be reversed without affecting performance.
OPERATION
De-Energized the pilot is pushed away from its seat. Pressure on the
nose port creates pilot flow through the spool and seat, lifting the spool
against a light bias spring, allowing full flow. Energized the armature
pushes the pilot onto its seat with a pre-determined spring force.
Pressure on the nose port acts against the pilot and lifts it, creating pilot
flow. When the pressure exceeds the spring force, the main spool lifts
allowing flow at the set pressure.
