For efficient operation, sugar mills must focus on improving operating costs and reliability. An automatic lubrication system plays a vital part in ensuring consistent uptime in operation. Our Dualine systems were developed nearly a century ago and are proven to be the most reliable method to deliver heavy greases over long distances. Proper lubrication of sugar mill equipment brings longer life to your machinery by protecting your essential components. You can rely on an automatic lubrication system to reach all necessary grease points to reduce overall wear.

Farval Dualine systems were developed nearly a century ago and are proven to be the best method to deliver heavy greases over long distances.
Lubrication points can be added easily without redesigning the total system.
A blockage between main line and bearing will not shut the system down; remaining bearings will continue to be lubricated.
There are positive lubrication indicators for each bearing point.
Lubrication discharge volume at each bearing is fully adjustable even after start-up.


Dualine lubrication systems are the ideal solution when continuous duty operation is required. There are several components that are used in designing a Dualine system, which include:


Measuring valves are the heart of the 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.


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.


Records the total lubricant delivered to each bearing and provides the end user with reliable and accurate data. Immediately communicates alarms to your PLC or our SC400 control, providing protection to all critical lubrication points.


DD Valve

DD Valves are dual line valves that are completely hydraulic in operation. They will deliver either oil or grease, are fully and individually adjustable in regard to discharge quantity and are equipped with operational indicators. Each DD valve serves two bearings. However, by a simple method of cross-porting, it will serve one. For example, a four-valve block can actually serve anywhere between four and eight bearings. DD valves can be supplied in several basic discharge capacities and are available in blocks consisting of one, two, three or four valves.


Spray Lance

Spray systems are used to lubricate large gear and pinion sets, found on ball mills, rod mills, kilns, etc. Each systems includes an air operated pumping station, a measuring valve panel, a spray nozzle, electrical controls, and a number of optional features. Gear face widths of 2" to 42" can be lubricated with nozzles and nozzle spacing designed accordingly. Since Bijur Delimon gear spray systems operate intermittently they can be thought of as film maintaining devices. The electrical controls provide broad cycling flexibility as well as fault monitoring and after blow to purge the nozzles.


DC42 Central Station

DC41 and DC42 stations can supply either oil or grease to such installations as bar mills, billet mills, blast furnaces, and sintering machines. The two systems differ in the way they alternately pressurize and relieve (reverse) the two supply lines as well as in the way they control maximum system pressure and end the lubrication cycle.


DS405 Lubrication Monitor

The DS405 is designed to monitor automatic oil or grease lubrication systems and is ideally suited to be used with our Lube Point Monitor. The DS405 records and displays the total lubricant delivered per channel (24 channels available). It also provides the end user with reliable, expandable and accessible data capture. Each channel can be individually configured with programmable warning and alarm levels.


Lube Point Monitor

The 55105 Lube Point Monitor is an accurate oval gear mechanism that incorporates two magnets into one of the oval gears. The body incorporates a reed switch which senses the magnet passing. Lubricant entering the 55105 causes the gears to rotate. Each single rotation of the oval gear equates to a displacement of .040 cu. in. (.65cc). The monitoring of the 55105 is done with any PLC. The feedback from the 55105 will assure that lubricant has reached the inlet of critical lubrication points.
