Multiple-Outlet Electrically Operated Oil Dispensers with Flow-Adjustment Valves

2 Outlets

4 Outlets

6 Outlets

Serve multiple lubrication points from a single location. These dispensers have a solenoid that automatically starts and stops flow so lubrication is dispensed only while equipment is running. When wired to a machine’s on/off switch, the solenoid remains closed until the machine is turned on. To adjust the flow to individual lubrication points, turn the dial on the corresponding valve. Dispensers can be used with any oil grade. Flow rate depends on temperature.

A solenoid automatically starts and stops flow so lubrication is dispensed only while equipment is running. When wired to a machine’s on/off switch, the solenoid remains closed until the machine is turned on. Turn the dial on the valve to adjust the flow of oil through the brush. Dispensers can be used with any oil grade. Flow rate depends on temperature.

Air-Powered Oil Dispensers

Connect these dispensers to your air system to pressurize the oil in the reservoir and atomize the spray. Dual regulators allow you to adjust the pressure of the oil and the atomized spray. Add a spray valve (sold separately) to direct the flow of oil. A removable filter prevents valve blockage. They have NPTF (Dryseal) threads, which are compatible with NPT threads.
