Product Overview
The 157B4734, 157B4116, 157B4792, 157B4128, 157B4735, and 157B4036 are members of the Danfoss Power Solutions PVE Series 4 electro-hydraulic proportional actuator family. These actuators mount directly onto Danfoss PVG32 and PVG100 proportional valve groups, converting electrical input signals into pilot pressure to precisely control main spool displacement for proportional flow control.
This series covers three core PVE actuator types to meet diverse application requirements—from high precision to medium precision, from active to passive fault monitoring, and from AMP to Deutsch/DIN connectors:
PVEA (Proportional Standard) : Standard proportional actuators — 157B4734, 157B4792, 157B4735
PVEM (Proportional Medium) : Medium-precision proportional actuators — 157B4116, 157B4128
PVEH (Proportional High) : High-precision proportional actuators — 157B4036
Manufactured to strict Danfoss original specifications, these actuators deliver consistent performance in material quality, machining precision, sealing integrity, and factory testing. Every unit undergoes 100% full-load simulation testing prior to shipment, validating pressure, flow, and directional cycling performance under real-world operating conditions. The actuators offer complete interchangeability—each model is directly replaceable by its corresponding Series 7 counterpart—with no modifications to mounting interfaces or electrical connections required, significantly reducing equipment downtime and retrofitting costs.

Key Technical Advantages
1. Three Precision Grades for Application-Specific Selection
The PVE series offers PVEA (Standard), PVEM (Medium), and PVEH (High) actuator types with hysteresis of approximately 2–6%, 25–35%, and 4–9% respectively. Users can select the optimal balance between performance and cost based on system control precision requirements.
2. Active vs. Passive Fault Monitoring — Dual Safety Modes
157B4734 and 157B4792 feature Active Fault Monitoring, continuously tracking actuator and spool position status and actively disabling solenoid valves upon detecting anomalies. 157B4735 features Passive Fault Monitoring, providing warnings without disabling solenoid valves—allowing the system to continue operating. Two modes accommodate different safety level and maintenance strategy requirements.
3. 157B4036 Built-in Direction Indication for Real-time Spool Status
The 157B4036 (PVEH-DI) features integrated Direction Indication, providing real-time feedback of spool movement direction. This greatly simplifies system commissioning and fault diagnosis—operators can verify correct actuator response without additional sensors.
4. Three Standard Connector Options for OEM Compatibility
This series offers AMP (1×4 or 2×4) , Deutsch (DT04) , and Hirschmann (DIN 43650-A) connector options, accommodating diverse OEM electrical interface standards for easy installation and convenient on-site replacement.
5. Wide Voltage Range for 12V and 24V System Compatibility
The series supports 11-32 V DC wide voltage input (157B4116 is fixed 12V version; 157B4128 is fixed 24V version), compatible with both 12V and 24V vehicle and industrial power systems. Ratiometric signal control ensures stable output across all voltage conditions.
6. High Ingress Protection for Demanding Environments
Achieving IP66 protection rating, the actuators effectively resist dust, oil mist, water spray, and high-pressure washdown. With a wide operating temperature range of -40°C to +90°C, they are ideal for demanding outdoor applications in construction and agricultural machinery.
7. Complete Interchangeability with Seamless S4-to-S7 Upgrade Path
All six models are directly replaceable by their corresponding Series 7 counterparts. The Series 7 versions offer further improvements in environmental durability, EMC robustness, and installation convenience—enabling true “plug-and-play” upgrades.
Application Areas
Mobile Construction Equipment: Excavators, loaders, cranes — implement proportional control
Agricultural Machinery: Combine harvesters, tractors — hydraulic actuator proportional control
Material Handling Equipment: Forklifts, telescopic handlers, aerial work platforms — hydraulic systems
Forestry Machinery: Harvesters, forwarders — proportional valve control
Truck-mounted Cranes & Loader Cranes: Boom extension, rotation, and luffing proportional control
Industrial Hydraulic Systems: Injection molding machines, presses, test benches — proportional directional control
Marine & Offshore Equipment: Deck machinery, winches — hydraulic control
Expert Maintenance Tips
1. Verify Model and Replacement Status — Critical Step
All six models are Series 4 products and have been officially discontinued, requiring replacement by corresponding Series 7 models. Confirm the latest model number when purchasing or replacing—old and new models are fully compatible in mounting interfaces and electrical specifications. Series 7 versions offer better environmental durability and diagnostic capability—replacement models are recommended for new purchases.
2. Connector Type Verification — Critical Selection Difference
This series uses three different connector types—NOT interchangeable:
AMP Connector: 157B4734, 157B4735 (1×4 AMP); 157B4036 (2×4 AMP)
Deutsch Connector: 157B4792 (1×4 Deutsch DT04)
DIN Connector: 157B4116, 157B4128 (1×4 Hirschmann DIN 43650-A)
Select the correct connector type based on your original valve configuration before installation.
3. Voltage Specification Verification — Critical for PVEM Selection
157B4116 is the 12V DC version; 157B4128 is the 24V DC version. While they share identical appearance and mounting interfaces, the voltage specifications differ—ensure correct model selection based on your system supply voltage. The Series 7 replacement 11166829 supports 11-32V DC wide voltage input, capable of replacing both 12V and 24V versions.
4. Active vs. Passive Fault Monitoring — Safety Strategy Selection
Active Fault Monitoring (157B4734, 157B4792) actively disables solenoid valves upon detecting anomalies—ideal for applications with stringent safety requirements. Passive Fault Monitoring (157B4735) provides warnings without disabling solenoid valves—allowing continuous system operation, suitable for applications where uptime is critical. Select based on your system safety strategy.
5. Fluid Cleanliness Management
PVE actuators require fluid cleanliness to ISO 4406 18/16/13. Install a filter with ≤10μm absolute filtration upstream of the PVG32 valve group and monitor fluid contamination regularly. Contaminants in the pilot oil directly affect spool control precision and response performance.
6. Pilot Pressure Verification
PVE series actuators require a pilot pressure of 13.5 bar (196 psi) for normal operation. Ensure the system provides stable pilot pressure above this value—insufficient pilot pressure will result in incomplete spool shifting or delayed response.
