TCBBB Counterbalance Valves

Item No.: TCBBB
Counterbalance valves are used to prevent oil from leaving a cylinder that is holding a load. Without the counterbalance valve, the load would move in an uncontrollable manner if oil pressure is lost for some reason.

TCBBB Counterbalance Valves



Max setting Pressure:    280bar

Flow Max:                      See Performance Chart

Internal Leakage:           5 drops/min/210bar

Filtration Of Oil:             25μm or better

Temperature:                -30℃ ~ +110℃

Cavity:                           T-11A see page209

Installation Torque:        40~45Nm



Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.

Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.

Reseat exceeds 85% of set pressure when the valve is standard set. Setting lower than the standard set pressure may result in lower reseat precentages.
