2. Function
2.1 Balancing and holding functions
1. During hoisting down, this valve selectively opens
and closes the motor outlet passage in
accordance with the pressure level of the motor
inlet pressure to control the speed of the load and
to prevent the load from falling under weight faster
than the hydraulic motor driving speed.
2. When the inlet pressure is below a certain level,
this valve closes the return passage to hold the
load at a desired position.
2.2 Overload relief function
When the circuit pressure rises above the preset
overload relief level, this valve vents it to protect
the circuit.
