VDP08

Among all hydraulic directional control valves used in the field of mobile equipment applications, the spool valve is the most
popular.

The sectional valve type allows construction flexibility. Salami directional control valves are modular construction and consist of an inlet/outlet section, up to 8 working sections and an end plate. All these elements are secured in one block by means of tie-rods.

Salami directional control valves have the following features:

• Special cast-iron body;
• Spool construction in steel, hardened and chromium-plated to obtain a higher surface hardness, a better corrosion resistance, and wearing reduction;
• Minimum tolerance between spools and body to obtain a minimum internal leakage;
• Interchangeability of all spools;
• Possibility of auxiliary valves on port A and 8
• Several spool controls.
