Proportional Directional Valves
The PDV – Proportional Directional Valve range from OMFB is engineered to deliver precise, repeatable, and fully controllable hydraulic performance in demanding mobile and industrial applications.
Designed and manufactured at OMFB headquarters in Italy, PDV valves combine high-quality mechanical construction with advanced electro-hydraulic proportional control.
Each PDV is built to order, configured to the customer’s exact operating requirements, and supported by local assembly, commissioning, and testing to ensure optimal performance from day one.

Manufacturing & Engineering Excellence
All PDV valve sections and core components are manufactured in OMFB’s Italian production facility, where strict quality standards and controlled processes ensure consistency and reliability.
Precision-machined bodies, high-quality spools, and proportional actuation systems are engineered to provide smooth flow modulation, stable pressure control, and long service life.
This in-house manufacturing approach allows OMFB to maintain full control over materials, tolerances, and functional performance, forming the foundation for dependable proportional control solutions.
Local Assembly, Configuration & Commissioning
Beyond manufacturing, PDV valves are locally assembled and commissioned to match each customer’s specific application requirements.
Valve configurations are selected based on operating flow, pressure, control logic, and machine duty cycle, ensuring the right specification is delivered — not a generic off-the-shelf solution.
Each assembly undergoes functional testing and verification, confirming correct proportional response, electrical compatibility, and hydraulic performance before delivery.

Product focus
PDV in Real-World Applications
PDV valves are widely used in applications where hydraulic precision directly affects output quality, such as line-marker trucks, cranes, specialised transport equipment, and process-driven mobile machinery.
In stop-start operations and long-duty cycles, the PDV’s proportional control ensures smooth transitions, consistent output, and repeatable results — even under varying flow demands.
By combining Italian manufacturing with local configuration and testing, OMFB delivers PDV solutions that perform reliably in real operating environments, not just on paper.
Quality Assurance & Testing
Every PDV assembly is subjected to functional and operational testing prior to delivery.
This includes verification of electrical actuation, proportional response, spool movement, and hydraulic integrity under controlled conditions.
The result is a valve that arrives ready to install, reducing commissioning time and ensuring confidence in system performance from first operation.
