Understanding Counterbalance Valves - Power Motion Both counterbalance valves and pilot-operated check valves can be used to lock fluid in a cylinder to prevent drifting However, a pilot-operated check valve cannot control an over-running load Whenever uncontrolled movement can occur from an overrunning load, a counterbalance valve should be used
Counterbalance valve question. : r Hydraulics - Reddit I've got a dual-acting cylinder with an internally piloted CB valve on the cap end, to hold a load from retracting the cylinder The CB valve is currently set too low, which is causing the load to drift I obviously need to adjust the valve higher (counter-clockwise) to stop the drift
How to Solve Load Control Issues with Counterbalance Valves Counterbalance valves primarily prevent uncontrolled movements in hydraulic systems They generate a counterforce to sustain loads in vertical or inclined positions, ensuring stability and safety
Typical Problems and Potential Solutions The problem this creates is that the opening on the counterbalance valve is so small that it is very difficult for it to modulate and will have a tendency to open and close at a high frequency causing unstable movement of the actuator
CBV Circuit Performance Improvement (2) | Sun Hydraulics It also delays the opening of the counterbalance valve Both help to further dampen the circuit but requires setup time and fine tuning on the machine and does cause leakage
