Counterbalance valve – with unloading function Counterbalance valve – with unloading function Overview This counterbalance valve is used to prevent load drop within a cylinder under overrunning load conditions and to control its lowering speed. Type indication Features 1. As the spool of the counterbalance valve is provided with the flow control part and seat part together, stable brake pressure can be obtained and at the same the leakage amount is small and the slipping-down amount of ram can be made very small. 2. When weight drop (fast feed state) is changed to pressurization (slow feed state), ram speed change can be adjusted and smooth operation can be performed by controlling spool valve closing speed with variable throttle. 3. The passage in the casing is composed of through holes and the flow resistance is small.
