PVG32 4-Section Multi-Way Valve (Detailed Overview)
I. Product Overview
The PVG32 4-Section Multi-Way Valve is a high-performance hydraulic control valve group designed for heavy-duty applications in construction machinery, agricultural equipment, and industrial vehicles. Its core features include independent control of multiple hydraulic functions through a four-section (quadruple) structure, along with high precision, reliability, and modular design, enabling it to adapt to complex operating conditions.
II. Technical Specifications
1. Operating Pressure Range:
Typically supports a maximum working pressure of 315 bar (specific models may vary slightly), suitable for high-pressure hydraulic systems.
2. Flow Rate Range:
Flow rates can reach 100-200 L/min depending on configuration, meeting the high-flow demands of medium to large-sized equipment.
3. Control Methods:
• Electro-Proportional Control: Achieves precise flow and pressure regulation via electromagnetic proportional valves, suitable for automated scenarios.
• Manual Control: Equipped with mechanical handles for emergency operation or debugging.
• Load-Sensing (LS) Function: Some models support load-sensing technology to optimize energy consumption and enhance system responsiveness.
4. Ports and Dimensions:
• The valve body adopts a modular design, supporting multi-section expansion (e.g., four-section, six-section, etc.).
• Port types typically comply with ISO/DIN standards, ensuring compatibility with mainstream hydraulic systems.
5. Environmental Adaptability:
• Operating temperature range: -20°C to +80°C (some models extendable to -40°C).
• Protection grade: IP65 or higher, suitable for harsh environments.
III. Core Functions
1. Multi-Section Independent Control:
The four-section structure enables independent control of four separate hydraulic actuators (e.g., cylinders, motors), facilitating synchronized or sequential control of complex movements.
2. Precise Flow Regulation:
In electro-proportional control mode, flow regulation accuracy can reach ±1%, suitable for scenarios requiring fine operation (e.g., excavator arms, agricultural machinery).
3. Energy-Saving Design:
Load-sensing technology reduces system overflow losses, lowers energy consumption, and extends the lifespan of hydraulic components.
4. Safety Protection:
Built-in overload protection, pressure compensation, and anti-shock functions enhance system reliability.
IV. Application Scenarios
1. Construction Machinery:
• Hydraulic arm control for excavators, loaders, and cranes.
• Independent drive of travel motors and swing motors.
2. Agricultural Machinery:
• Hydraulic steering and actuator control for harvesters and tractors.
• Precise regulation of hydraulic suspension systems.
3. Industrial Vehicles:
• Hydraulic lifting and steering control for forklifts and aerial work platforms.
• Hydraulic drive for automated logistics equipment.
V. Advantages Analysis
1. Modular Design:
Supports multi-section expansion, allowing users to flexibly configure the number and functions of valve groups based on needs.
2. High Reliability:
Adopts high-quality materials and sealing technology, adapting to high-temperature, high-pressure, and high-pollution environments.
3. Convenient Maintenance:
Modular structure facilitates easy disassembly and repair, reducing downtime.
4. Strong Compatibility:
Seamlessly integrates with mainstream hydraulic systems (e.g., Rexroth, Kawasaki), lowering integration costs.
