Please note: Port #3 on the Graduated Capillary Micro-Splitter Valve is designed for use with an appropriately-sized Micro Tight™ tubing sleeve, available separately.
Please Note: The Valves are designed to work when both effluent flow path pressures are nearly identical. However, the split flow path will often have higher back pressure than the waste flow path, making it hard to achieve any split flow at all. There are two possible solutions. First, you may place a Back Pressure Regulator on the waste flow path that is equal to or slightly greater than the pressure on the split flow path. The second alternative is to switch the two effluent pathways such that the split flow pathway is attached to the "waste" port on the valve and the waste flow pathway is attached to the "split" port on the valve. This second method may, however, result in a loss of adjustment sensitivity.
CAUTION! Do not tighten the valve past the physical zero point on the adjustment knob. Doing so may damage the valve. This valve is considered "fully open" after the knob has been rotated 2 ½ complete turns counterclockwise from the physical zero point. Any further opening should be avoided so as to not damage the valve's components.
