Rickmeier RSN 1½″ SAE Pressure Relief Valve – NEW
Rickmeier RSN 1½″ SAE Pressure Relief Valve is a factory-new, OEM-grade hydraulic safety device meticulously engineered to protect fluid-power systems from excessive pressure spikes and ensure reliable operation. With its exact “RSN” model code and 1½″ SAE port size clearly identified, this valve offers full compatibility and traceability within heavy-duty hydraulic circuits, making it ideal for use in mobile equipment, industrial machinery, offshore modules, and power pack systems where robust overpressure protection is critical.
Constructed with a durable steel body and precision-machined spool and seating surfaces, the valve delivers rapid and accurate pressure relief. Its direct-acting, spring-loaded mechanism opens upon reaching a predetermined pressure setting—typically up to 250 bar—allowing excess flow to bypass safely and prevent component failure. This action protects pumps, motors, hoses, and actuators from overload conditions without compromising system performance or introducing significant pressure drop during normal operation.
The compact cartridge-style design with SAE ports ensures seamless integration into manifold blocks or inline piping setups. Adjustability is a key feature: a fine-threaded adjustment screw allows precise setting of relief pressure, with a locking cap safeguarding against unwanted changes during intensive use. Internally hardened seats and anti-extrusion seals deliver low internal leakage and minimize wear, ensuring stable function even under repeated cycling and in contaminated environments.
Engineered for longevity, the RSN valve incorporates full-flow bypass capacity to handle large volumetric surges without chattering or premature wear. Its spring and spool assembly is housed in a robust casing equipped with corrosion-resistant finishes to withstand harsh conditions such as marine spray, chemical exposure, and temperature extremes. Classified for industrial duty, it meets and exceeds ISO and SAE performance standards for hydraulic relief valves.
In summary, the Rickmeier RSN 1½″ SAE Pressure Relief Valve provides dependable, adjustable overpressure protection in a compact, service-friendly package. Ideal for heavy-duty and critical hydraulic systems, this new valve ensures system integrity, safety, and operational continuity—making it a smart investment for engineers and maintenance teams seeking reliable pressure control solutions.
