416440-L

The 416440-L hydraulic accessory is produced by Vickers for the Vickers Hydraulic Accessories series and is intended to manage fluid flow in automated hydraulic systems. A displacement of 45.4 cc per revolution (2.77 in³ per revolution) delivers a predictable volume for each shaft rotation, facilitating calculated circuit flow. The unit sustains 210 bar (3000 psi) as its maximum continuous pressure so it can operate in medium-pressure circuits without fatigue. A top speed rating of 2700 rpm permits rapid cycling when high throughput is required. Left-hand counterclockwise rotation aligns the shaft direction with installations that drive pumps from the opposite side. Sealing is handled by an O-ring design, and reference number 154095 identifies the specific O-ring used for replacements.

Total mass is 8.00 lb, allowing technicians to mount or service the component without lifting equipment. A height of 3.81 in, a width of 3.81 in, and a length of 3.55 in keep the housing compact so it fits on crowded manifolds. Minimum speed capability is 600 rpm when outlet pressure is below 1000 psi, ensuring consistent lubrication during light-load operation, while the minimum allowed speed rises to 1000 rpm when pressure exceeds 1000 psi to preserve hydrodynamic film stability. These dimensional and speed limits help designers balance flow, pressure, and space when integrating the accessory into automated hydraulic machinery.
