Description
It provides static and dynamic motion control by regulating flow and pressure IN and OUT of the hydraulic motor at ports C1 and C2. When installed close to the motor, it can stop runaway in case of hose failure. The check sections allow free flow into the motor and prevent reverse movement; the pilot assisted relief valves control the movement when pilot pressure is applied. The relief valves operate with 2-levels pressure setting, both adjustable: higher setting when flow is delivered to the motor, and lower setting when flow is discharged by the motor during stopping. A system of check valves allows cross line relief and an optional make-up port (T) allows to compensate for any volume change. Through port C3, a shuttle valve directs either V1 or V2 pressure to the spring actuated brake for brake releasing.
Note: aluminium bodies are often strong enough for operating pressures
exceeding 210 bar (3000 psi), depending from the fatigue life expected in the
specific application. If in doubt, consult our Service Network.
