wo Gun Systems

Each line in a two gun system must have a shutof valve to relieve fluid pressure if the fluid line becomes clogged, and to isolate one gun for servicing while the other is in operation. Director valve 214–71 mended for both purposes. Use elbow 100–840 to direct the outlet flow from the drain valve in a safe direction to a waste container. Use reducer bushings 100–176 and 100–206 to connect the valve to the outlets of fluid filter 214–625.

In the draining mode, the valve handle is turned away from the elbow (marked DRAIN on the valve housing); in the operating mode, the handle is turned toward the elbow (marked CIRC on the housing).
