The 108 series valve is designed for high pressure low flow applications. This valve is well suited for flow control in oil delivery systems in service garages, auto dealerships and lube centers. The 108 valve can have flow rates up to 6 gpm depending upon pressure. The spool valve has a maximum internal leakage of .25 cc/min at 3000 psi. The valve dimensions are 4"h x 1"w x 2"d. It is reccommended that 25 micron filtration be installed ahead of the valve to increase valve life and reduce maintenance.
