Vent Valve, Air

The Vent Valve is operated by compressed air from the same source which operates the pump. When pump is in operation, air pressure keeps the vent valve closed and lubricant is directed through the outlet and to the injectors. When air to the pump is shut off, vent valve opens and supply line pressure vents back into the reservoir.

• Vent Valve for Centromatic® Air-Operated Grease Pumps

Lincoln Centro-Matic® systems and components are made to match your application. Systems can service one machine, different zones on one machine, or even several separate machines. Regardless of the application, the principle of centralized lubrication remains the same: a central pump station automatically delivers lubricant through a single supply line to the injectors. Each injector serves only one lubrication point and may be accurately adjusted to deliver the precise amount of grease or oil required.

Centro-Matic systems give you multiple advantages over other designs. Simplicity Systems are easy to understand, install and maintain. You realize savings right from the start because one lubricant supply line means lower installation costs. Powerful Pumping Unit Centro-Matic systems dispense either grease or oil in measured quantities, unaffected by normal temperature or viscosity changes. For large systems, Lincoln’s single-line design and powerful pumps mean injectors can be located long distances from original refinery containers or bulk lubricant tanks. External Adjustment Lubricant injectors are externally adjustable without special tools so each bearing can receive the correct amount of lubricant. No under- or over-lubrication at individual points.
