Swing motor
(6) Anti-reaction valveAnti-reaction valve (6) is an integrated valve within the swing motor head. The anti-reaction valve is used to reduce the reverse swing effect when the swing operation is stopped.During a swing stop, it is difficult to smoothly stop the upper structure and implements at the desired position due to the mass (weight and size) of the upper structure. The pressure of the blocked oil in the outlet side of the swing motor goes back to the motor rotary group. The upper structure begins to swing in the opposite direction. Anti-reaction valve (6) prevents the blocked oil from flowing back to the motor rotary group.Neutral
