Counterbalance valves — also called overcenter valves — hold loads securely, prevent uncontrolled run-away, and allow smooth, controlled lowering in hydraulic systems. FPD supplies the full range: single-acting and double-acting variants in standard, compact, super-compact, and motor-flangeable configurations. Whether you need a valve to hold a suspended load on a crane, control descent on a forestry machine, or protect a drive motor circuit from overrunning, there's a model to suit.
