Our concept is to offer a large variety of hydraulic manifolds at reasonable prices and prompt deliveries.
It is the responsibility of the customer to select the appropriate material. When doing so, the following factors should be taken into consideration:
• Pressure: Normally, aluminum is rated for 3,000 PSI while steel is rated for 6,000 PSI. The pressure rating of the valves itself should also be taken into consideration.
• Heat: Steel should be used when the valves generate high heat such as pressure relieving and pressure reducing valves. The coefficient of linear expansion for aluminum is twice that of steel cartridges and plugs. Therefore they will expand at a different rate and may loosen.
• Erosion: If the oil velocity is very high as the oil leaves the cartridge, there is a danger of erosion on the walls of the cavity. In this case steel would be a better choice.
• Corrosion: If corrosion is a factor, a special coating may be required.
• Weight: Weight is normally not a factor since the manifold itself is considerably smaller than the rest of the equipment. However, if weight is a concern, a steel manifold will weight about three times as much as the same manifold in aluminum. › View
