Sleeves Bushings

Sleeves - Bushings

Gervasoni sleeves and bushings house and guide the spool within hydraulic valves and solenoid valves, creating the precision coupling that regulates fluid flow. Machined from steel and special high corrosion-resistant steel, they are ground on internal and external diameters to tolerances defined for each part number, ensuring sealing and axial smoothness even under the most demanding operating conditions. The performance of the entire valve depends on the precision of this coupling: a principle that guides every stage of Gervasoni's manufacturing process.
