Information About 157B4734
The 157B4734 is a PVEA Series 4 actuator with a PVE32 O-ring mounting interface. It operates from an 11–32 VDC supply and connects through a single four-pin AMP JPT SAAB connector. The IP66-rated assembly uses hydraulic pilot actuation to position the valve spool according to the electrical command. Active fault monitoring disables the solenoids when a fault is detected and provides automatic recovery.
Key Features:
- Proportional Operation: Regulates valve spool movement according to a ratiometric command signal.
- Low Hysteresis: Specified hysteresis is 2.0% for repeatable control response.
- Wide Supply Range: Accepts 11–32 VDC for compatible machine electrical systems.
- AMP Connection: Uses one four-pin AMP JPT SAAB connector oriented upward at 90°.
- Active Fault Monitoring: Disables solenoid operation upon a detected fault.
- Automatic Recovery: Supports recovery after the detected fault condition clears.
- Environmental Protection: IP66 enclosure resists dust ingress and powerful water jets.
- Hydraulic Interface: Incorporates the PVE32 O-ring interface for compatible valve assemblies.
The 157B4734 delivers the reliability and precision required for proportional hydraulic valve actuation in mobile equipment.
