Product Overview

The Danfoss PVG 32 represents the pinnacle of modular hydraulic technology, serving as a load-sensing proportional valve group designed to provide maximum flexibility and uncompromising control. This flagship multi-way directional valve allows for thousands of configurations, ranging from simple load-sensing directional control to advanced electronically controlled, CAN-bus integrated systems. Engineered for high-performance mobile machinery such as cranes, excavators, and forestry equipment, the PVG 32 precisely manages oil flow and pressure to multiple functions simultaneously. By decoupling the flow from the load pressure, it ensures smooth, independent movement of every hydraulic actuator, regardless of changes in work conditions. Its modular architecture enables engineers to assemble a custom control center that scales perfectly with the machine’s complexity, delivering the high-precision maneuvering required for modern industrial and mobile hydraulic power.

Technical Configuration & Modularity

Total Stack Width Calculation

Because the PVG 32 is a modular system, the total width (W) of the valve group depends on the number of basic modules (sections) installed. Use the following formula for your installation planning:

Total Width = 82 mm (Inlet + End Plate) + (Number of Sections × 48 mm)

Engineering Installation Guide

Tie-Rod Tensioning

Assemble the modules and insert the tie-rods. You must tighten the tie-rod nuts to a uniform torque of 28 Nm. This ensures the O-rings between the modules compress correctly to prevent external leaks without distorting the precision-ground valve bores.

Mounting and Port Connections

The PVG 32 features three mounting holes on the inlet and end plates. Always mount the valve group to a flat surface to prevent mechanical stress on the stack. Use G 1/2 or G 3/4 fittings for the A/B work ports and ensure the tank (T) line remains as short as possible to minimize backpressure.

Engineering Advantages

The PVG 32 excels in environments where multi-tasking and precision are non-negotiable. Its ruggedized construction withstands the heavy vibration and extreme temperature fluctuations common in offshore and construction sites. The valve’s compatibility with the Danfoss PLUS+1® platform allows for seamless integration into a total machine control system, providing OEMs with a "digital-ready" hydraulic backbone. The pressure-compensated design prevents dangerous load-drop events and ensures that safety-critical functions, such as crane boom movements, remain predictable and smooth.

Delivery & Logistics

Delivery time: 3-5 days when payment finish.

Shipping Carriers: BY DHL/FEDEX/UPS.

Packaging: We utilize heavy-duty reinforced crating and anti-static protective wrapping. Every PVG 32 module is shipped in factory-sealed packaging to ensure the precision-ground spools and sensitive electronic actuators arrive in perfect working order.

Technical FAQs

Q1: Can I mix manual and electrical sections in the same PVG 32 stack?

A1: Yes, the PVG 32 modular system fully supports a combination of manual, hydraulic, and electrical actuators within one stack.

Q2: What is the benefit of the LS (Load Sensing) signal?

A2: The LS signal tells the variable displacement pump to only provide the pressure and flow actually required, saving energy and reducing oil heating.

Q3: How do I adjust the maximum pressure for an individual work port?

A3: You can install shock and suction valves (PVLP) directly into each basic module to protect specific actuators without affecting the rest of the system.
