Vonberg pressure controls are available in two product types — relief valves and counterbalance valves. Two body styles are available are in-line and threaded cartridge.
Relief valves limit maximum system pressure or maintain a desired pressure within a hydraulic circuit. Relief valves are also available with a free reverse flow option that limits maximum system pressure or allows sequencing of pressures within a circuit. Vonberg manufactures 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 overcenter load holding applications, and are available in either industry standard or t-series cavity designs.
