Counterbalance valve 25/221265 JCB Loadall, genuine

Counterbalance valve 25/221265 is a genuine JCB part for the JCB Loadall telehandlers.

The load holding (counterbalance) valve fits on the load-bearing side of a cylinder: with the control in neutral it blocks the oil and holds the load, and when operated it opens under pilot pressure for a slow, smooth descent. If a hose bursts, it stops the boom or load dropping uncontrolled, making it an important safety element. A faulty valve lets the load creep down, causes jerky movements or stops the arm being lowered. The cartridge is supplied new with a factory setting. Load holding valves are fundamental to the safety of lifting machines, so they are replaced only with the same part number. The setting is chosen above the cylinder pressure at full load. The valve sits in the block on the cylinder and protects against a hose burst. The valve is made of steel.
