A spring loaded plunger holds the check plunger over, which in turn holds the nylon poppet open, allowing the cylinder to float. The check plunger may be shifted out of the detented position by merely pulling the valve spool "out" to pressurize the open work port. Single Acting Check Plunger (Special Unloading) A special single acting unloading check plunger is available which prevents the pump flow from going over system relief each time a single acting cylinder is being retracted and it also provides simultaneous operation of other functions either up or down stream. Adjustable Travel A spool travel limit adjusting screw is available to limit the spool "In" or spool "Out" travel. This allows the raising or lowering speed of a cylinder to be adjusted without the use of orifice plates., Bar 1,5 Bar Bar 3,5 3,,5 1,,5 18 16 1 1 1 8 6 18 16 1 1 1 8 6 Neutral Flow Pressure Drop 1 [3,8] [7,6] LPM [GPM] Work Port Pressure Drop Flow: Work Port to Return One 1 [3,8] 1 [3,8] [7,6] [7,6] Two Adjacent to Return GPM [LPM] 3 [11] 3 [11] 3 [11] Three Second from Inlet Adjacent to Inlet [15] Third from Return Second from Return [15] Work Port Pressure Drop Flow: Inlet to Work Port Third from Inlet [15] [6] [5] [] [3] [] [1] [ ] 5 [19] [5] [] [15] [1] [ 5] [ ] 5 [19] [5] [] [15] [1] [ 5] [ ] 5 [19] GPM [LPM] Tests performed with oil viscosity 15 SUS at 37.7 C [1 F] oil temperature 5.
