Relief valves limit maximum system pressure or maintain a desired pressure within a circuit. They are also available with a free reverse flow option that allows sequencing of pressures within a circuit. Vonberg offers both direct acting and differential area relief valves.
Counterbalance valves allow free flow in one direction, while flow in the opposite direction is controlled by a specified pilot ratio and relief pressure setting. They are intended for motion control and over center load holding applications, and are available to fit either industry standard or T-series cavities.
