Cam Roller Valves

Cam roller models are operated with a cam that shifts the spool. To fully shift the valve, the cam is pushed toward the valve. Normally the cam is contacted by a mechanical ramp to cause the shifting of the valve. On all cam valves, there is no positive detent for centering the spool (Position "B").
