2. 2-Position, 2-Way Manual Valve Used With Single-acting Cylinder (Figures 2 & 3)
NOTE: Some valves return fluid to the reservoir or bladder when the pump is not running or when the
valve control lever is shifted. The correct valve must be used per application, especially when
lifting a load.
WARNING
Valve (No. 9561) works the same as a manifold if the pump is operated with the valve
in the RETURN position. In this position, the cylinder will advance when the pump is
running and
retract
when the pump is not running.
Never use valve (No. 9561) in the RETURN position when lifting a load!
