Use these valves with manual and electric pumps to dispense different amounts of oil from multiple lubrication points. They have a check valve to prevent backward flow. To connect to tubing, use a compression nut and sleeve (sold separately).

Flow rate trade number indicates the relative amount of oil each valve delivers. For each increase in trade size, the amount of oil delivered approximately doubles. For example, 0 delivers twice the amount of oil that 00 delivers. In a system with two lubrication points, the lubrication point connected to 0 will receive 2/3 of the oil dispensed, and the lubrication point connected to 00 will receive 1/3 of the oil dispensed. In general, valves with lower relative flow rates are better for cycling systems; valves with higher relative flow rates are better for continuous recirculation systems.
