Proportional directional
spool valves type size2RT-PSL/V-2
Product overview
Load-sensing Proportional directional spool valves types series 3 can be used in constant displacement pump and variable displacement pump
hydraulic system. Stepless speed regulation can be carried out on the cylinder or motor by means of electronic control, manual and hydraulic control.
The output flow is only proportional to the input current signal or handle lever, and the speed is independent of the load, so several actuators can work
at different pressure and speed independently until the total required flow rate of the actuator is greater than the maximum flow rate that the pump
can provide.
The valve contains three functional blocks: connection block, directional valves and end plate. Each function block has different functions for option.
Maximum of 12 sections in each bank of valve.
RT-PSL-2 Connection block
The connection block has two basic forms
l)The PSL connection block is equipped with 3-wayflow control valve, which is used for the constant displacement pump system (open centersystem)
2)PSV type connection block is used in variable displacement pump system (closed center system), constant pressure system, or system with PSL type
proportional directional spool valve supplying oil in parallel as downstream proportional directional spool valve.
Note: The connection block of size 2 can be retrofitted to switch between PSL and PSV functions
Size 2 Twin solenoid parameters
Size 2 Proportional directional spool valves adopt wet twin solenoid, the hydraulic oil can enter inside the twin solenoid for protection, rust prevention
and lubrication, Therefore, no lubrication maintenance is required. Specific parameters are as follows:
