Hand Manual Lever Valves

Manual lever/hand models are operated with a handle that shifts the spool. The standard handle position of the lever for a 3-position valve is the center of the valve (Position "B"). To fully shift the valve, the handle is pulled towards the operator (Position "A") or away from the operator (Position "C"). On 2-position valves, there is no positive detent for centering the spool (Position "B").
