The URG2 06 C 13 unloading relief valve belongs to the Pressure Control Valves series produced by Vickers and is applied in hydraulic automation to relieve and divert flow when system pressure reaches a preset level. It is a pilot-operated, two-stage design, a configuration chosen to give stable pressure regulation and fast unloading once the pilot threshold is reached. The adjustable pressure range of 500–2000 psi allows the user to select a relief point suited to medium-pressure circuits, while the 3000 psi maximum operating pressure provides a safety margin for pressure spikes. A rated flow capacity of 25 gpm enables the valve to handle typical pump outputs found in mobile and industrial machines. Subplate mounting permits quick removal from manifolds without disturbing pipework, and the SAE 12 (1-1/16-12 UN) port thread matches common hydraulic adapters used in North American installations.
A cast-iron body grants strength and wear resistance for continuous duty, and nitrile seals maintain containment of petroleum-based fluids without swelling or loss of elasticity. The valve returns pilot and case leakage internally, reducing external hose requirements and simplifying plumbing. Operation is restricted to petroleum oils, a compatibility that aligns with most standard hydraulic fluids, and system oil must be maintained at or cleaner than ISO 4406 19/17/14 to protect the precision pilot passages. A working temperature window from –4 to +158 °F allows reliable function in unheated plants and warm equipment bays. Overall dimensions of 160.3 mm in length and 187.15 mm in height help engineers confirm stack-up space inside compact power units.
