SINGLE COUNTERBALANCE VALVE FOR CLOSED CENTER VCCR OVERCENTER VALVE SIMPLE EFFECT SEMI-COMPENSATED FOR IN-LINE INSTALLATION WITH EXTERNAL PILOT LINE With the Oleoweb VCCR counterbalance valves it is possible to support a suspended load and control its movement by eliminating vibrations or too fast and dangerous lowering. Equipped with a valve body with BSPP-GAS threaded ports, the VCCR overcenter valves are designed to be installed in-line within the hydraulic system in compliance with the spaces available on the machine. The single overcenter valves of the VCCR series are designed to ensure the stability in the working position of a hydraulic actuator with suspended load, and to control its movement in only one direction (usually the descent phase), leaving the opposite side powered by free flow; thanks to the BSPP-GAS threaded ports, it can be installed in-line into the hydraulic system. By feeding the line opposite the load, the pilot line manages the partial opening of the descent channel allowing control of the actuator movement and avoiding the phenomenon of cavitation thanks to the action of contrasting the gravitational force.
