TFS works with Parker Hannifin products and systems

Parker Hannifin: the global leader in fluid power

Founded in 1917 in Cleveland, Ohio, Parker Hannifin Corporation is the world’s largest company in fluid power, motion, and control technology. The group operates with over 62,000 employees in 50 countries, has revenue exceeding $19 billion, and is listed on the NYSE. Parker’s portfolio includes nine integrated technologies: hydraulics, pneumatics, filtration, fluid connectors, climate control, electromechanical, sensors, industrial processes, and engineered materials. The brand is particularly widespread in the aerospace, marine, oil & gas, and industrial machinery industries.

For the Italian industrial hydraulics sector, Parker’s key portfolio includes the P1/P2 and PV series variable-displacement axial piston pumps (interchangeable with Bosch Rexroth A10VSO), the D1VW series directional valves in the CETOP/ISO 4401 NG6 standard, the D31/D81 proportional valves with integrated electronics, the Roller Stator orbital motors, and the Calzoni radial piston motors (acquired by Parker in the 1990s). Rounding out the range are Parker Triple-Lok and EO/EO-2 fittings, Parker Filtration filters, and Parflex hoses, all widely used in the retrofitting of Italian systems.
