Rexroth Hydraulic Relief Valve 3DR10P5-6X100Y 00M Iron Materail For Oil And Gas Industry

The Rexroth hydraulic relief valve is available in various structural configurations including film type, spring film type, piston type, lever type, and bellows type. It can be designed as single seat or double seat, with valve disc positions categorized as positive action type or reaction type.

This pressure reducing valve automatically maintains stable outlet pressure by adjusting inlet pressure through medium energy. From a fluid mechanics perspective, it acts as a variable throttling element that changes flow rate and fluid kinetic energy to achieve pressure reduction. The control system balances pressure fluctuations with spring force to maintain consistent downstream pressure.

For higher output pressures or larger diameters, the pilot-operated design overcomes limitations of direct-acting valves, reducing output pressure fluctuations during flow changes and minimizing structural size. Pilot pressure can be supplied internally or externally.
