PUMPS:Variable delivery open circuit, unidirectional with 2 basic control options; - manual lever and pressure compensator.
Manual lever controlled pumps are useful for those applications which require variable output speeds from an open circuit system.
Pressure compensator pumps are commonly used with pressure port closed valving on multifunction systems.
The Pressure compensator units are available with remote pressure control and with means for externally adjusting the maximum and minimum displacement. When used with a minimum displacement limit they are ideal for HIGH-LOW systems for presses etc. MOTORS: These units can also be used as variable motors in open or closed circuits. The displacement is controlled by a manual lever.
Spool Type Valves Direct Solenoid Operated Wet Armature Solenoids
4 ways,3 position.
Flow rates are based on a 10 bar pressure drop using oil to ISO VG 46 at 50˚C
Pressure compensated
Designed to supply two circuits with a single pump.
Maximum pressure - 210 BAR (3000 PSI)
Lever is adjustable through 90˚
Port "IN" = Pressure port
Port "CF" = Controlled flow
Port "EX" = Excess flow (can be used to power a second circuit)

This valve controls a moving load in both directions preventing it from moving ahead of the pump and locks the load in any position on U1 and U2. This valve permits free flow from D1 to U1 & D2 to U2 and blocks the flow from U1 to D1 to D2 until a pilot pressure generated at D1 or D2 is sufficient to pilot the U1 or U2 port open.
It is utilised in combination with a closed centre spool valve. It is recommended to fit a port relief in this application.
