Pressure Regulation: The hydraulic fluid control pres-
sure reducing valve (J) reduces the hydraulic oil pres-
sure to the operating pressure required for application.
Flow Regulation: The hydraulic fluid control valve (K)
limits the maximum amount of oil flow to the motor to
keep the hydraulic motor within the recommended cycle
rate limit. This prevents pump runaway. The limit on the
™
Dyna-Star is 60 cpm. The limit on the Power-Star
66 cpm.
Pump Isolation: The hydraulic fluid control (A and B) has
ball valves on the supply and return sides of the mani-
fold. The ball valves isolate the hydraulic fluid control
and pump for servicing without stopping the hydraulic
power source.
