OPERATION

The valve regulates flow from port `P` to port `R`and by-passes the excess to port `T`. The regulated flow from port `R`remains virtually constant regardless of load variations, and can be adjusted from zero to 70 litres/min. maximum by turning the adjustmentscrew counter-clockwise. The maximum pressure at port `R` is set by adjusting the pressure relief setting. The blocking of port `R` is not recommended as it will cause pressure build-up and overheating in the hydraulic system.
