DOSING VALVES are reliable and efficient static dosing valves, that dispense a lubrication quantity between 10 to 750 mm³ per stroke. For pressure build up, every dosing element dispenses the prescribed dosing volume (piston surface per stroke), ensuring a precise and failsafe amount of lubricant to the lubrication point. During the following relief phase, the lubricant is restacked in the dosing valves for the next lubrication process. Structure and mode of action Metering procedure: If pressure is built-up at the entrance of the body, then the lubricant flows to the lower surface of the seal via the return valve. The seal with the piston moves against the force of the spring up to the end stop on the dosing nozzle. Metering is done, whereby, the displaced lubricant flows through a transverse and longitudinal bore to the centre of the outlet. Relieving procedure: If pressure at the entrance falls below the relief pressure, the return valve lifts as a result of the tensioned spring and releases its longitudinal bore. The lubricant flows through the longitudinal and transverse bore at the centre from the lower to the upper side of the piston, which moves up to its lower end stop. The valve is then in the initial position and is ready for the next metering. DOSING VALVES can be used with all pumps of the single line system. APPLICATION These valves connected to the pump are perfect to transfer the respective quantity of lubricant to the friction point on small machine application, machine tools, wood processing machines, packaging machines, sheet metal and single point lubrication with oil or fluid grease.
