Description
The HAWE CRQ-3A Relief Valve is a compact, kick-down, pilot-operated balanced piston hydraulic cartridge relief valve engineered to provide efficient pressure unloading and dependable overpressure protection in demanding hydraulic systems. Designed for mobile and industrial fluid power applications, the CRQ-3A series delivers stable pressure control with rapid unloading characteristics that help reduce heat generation, energy consumption, and hydraulic system stress during bypass conditions. Featuring a compact T-3A cavity design, operating pressures up to 350 bar (5,076 psi), and flow capacities up to 200 L/min, these hydraulic relief valves are ideal for hydraulic manifolds, mobile machinery, industrial equipment, hydraulic power units, and custom unloading circuits requiring pilot-operated relief functionality with low unloaded pressure characteristics. The HAWE CRQ-3A series is available in multiple pressure adjustment ranges from 1.7 bar up to 420 bar and offers several adjustment configurations including leakproof hex socket screws, lockable handknobs, and optional stainless steel tamper-resistant covers for secure pressure tuning and reliable operation in harsh environments. Designed with balanced piston construction, low leakage performance, and fast pressure response characteristics, the CRQ-3A valve series helps improve hydraulic system efficiency, pressure stability, and overall reliability in demanding fluid power applications. Warning: Improper valve selection, pressure adjustment, installation, or hydraulic system integration may result in uncontrolled pressure conditions, hydraulic system failure, equipment damage, serious injury, or death. Always verify system compatibility, follow manufacturer installation torque specifications, ensure pressure settings are properly configured for the intended application, and adhere to all hydraulic safety procedures before operation.
