1. Product Overview
The Danfoss MCV series electronically controlled valve module is a modular proportional control valve bank designed specifically for mobile and industrial machinery. As a next-generation intelligent Hydraulic valve platform, it integrates proportional solenoids and high-precision spools to provide flexible, fast, and precise flow and direction control for modern hydraulic systems, widely meeting the automation needs of off-road vehicles and construction machinery.
2. Core Control Functions
In a typical hydraulic system, this Hydraulic valve module receives PWM electrical signals from the machine controller (such as the Danfoss PLUS+1 system), driving the spool to produce an opening proportional to the current, thereby achieving stepless adjustment of cylinder speed or motor torque. When the hydraulic system requires combined movements, the internal load-sensing (LS) network of the MCV module dynamically distributes flow, avoiding motion imbalance caused by load differences and significantly reducing energy losses in the hydraulic system.
3. Modular Structure and Features
· Plug-and-Play Design: Each Hydraulic valve slice adopts standardized assembly interfaces and can be freely combined into multi-section valve banks, greatly simplifying the plumbing layout of the hydraulic system.
· Electro-Hydraulic Closed-Loop Control: Optional spool position feedback sensors give this Hydraulic valve high repeatability and extremely low hysteresis, ensuring the actuation precision of the hydraulic system.
· Multi-Function Integration: In addition to the main directional control function, auxiliary functions such as pressure compensators and secondary relief valves can be integrated into the same Hydraulic valve module, enhancing system integration.
4. Technical Specifications at a Glance
· Rated Pressure: Typically up to 350 bar (high-pressure version), meeting the demanding requirements of hydraulic systems.
· Maximum Flow: Up to 100–150 L/min per section, depending on the port size.
· Supply Voltage: Commonly 12 V or 24 V DC, compatible with vehicle electrical systems.
· Control Mode: Direct-acting proportional solenoids, supporting CAN bus communication (via companion electronic controllers).
· Fluid and Filtration: High-quality hydraulic oil is required, and ISO cleanliness levels must be maintained to protect the precision moving parts of the Hydraulic valve.
5. Typical Application Scenarios
Danfoss MCV series Hydraulic valves are extensively integrated into the following mobile and stationary hydraulic systems:
· Crane telescopic boom and luffing control
· Excavator swing and bucket combined movements
· Agricultural harvester header and steering control
· Municipal sanitation vehicles (such as garbage compactors and sweepers)
6. Application Value
With its compact modular form and electro-proportional control capability, the MCV series Hydraulic valve enables equipment manufacturers to build smarter hydraulic systems that are more responsive, more energy-efficient, and more comfortable to operate. Its plug-and-play nature also helps shorten machine commissioning cycles and reduce the overall maintenance costs of the hydraulic system.
