Dualine Lubrication Systems
Dualine lubricating systems are found in virtually every industry in which continuous duty operation is required. From steel production to pulp and paper, from mining equipment to machine tools, automatic application of the lubricant provides significant benefits to the equipment user. There are several components that are used in designing a Dualine lubrication system, including valves, lubricators, reversing valves, central stations, controllers, and spray systems.
Measuring valves are the heart of Dualine lubrication systems. They are mounted close to the lubrication points and are hydraulically operated by pressure from the first and then the second of the two supply lines. On each pressurization cycle, they indirectly discharge fixed volumes of lubricant to the bearing or lubrication point.
Manual, electric and pneumatic lubricators store and pump lubricant to Dualine valves throughout the system.
These valves change the flow and direction of pressure, which causes divider valves in the system to cycle.
Central stations include lubricator, cycle switch and reversing valve. Some versions are mounted on a plate for easier installation.
Programmable controllers give you access to key system functions, such as system on and off, and can control what happens when there is a problem in the system.
Used to lubricate large gears and pinion sets.
- Economical for a system having more than 20 bearing points.
- Lubrication points can be added easily without redesigning the total system.
- A blockage between feed line and bearing will not shut the system down; remaining bearings will continue to be lubricated.
- Positive lubrication indicators for each bearing point.
- Ability to positively displace a broad range of lubricants from light oil to grade 2 grease.
- Lubrication discharge volume at each bearing is fully adjustable even after start-up.
