Thick walls and large valve port diameters of Model LC maximize oil flow. Units can be mounted horizontally or vertically with or without flange, and in any orientation with L-brackets or through-bolt feature in valve surface. Matching gasket prevents contamination during vertical installation on tank reservoir. In parallel circuits, DO3 and DO5 valve sizes are available with 1-6 stations in normal spacing and 2-4 stations in wide spacing.
