Product Overview
3026758 pressure regulator valve seat (SEAT,PRS REGULATOR VALVE) is a core precision base component customized for Cummins M11, ISM11 and QSM11 series diesel engines. Installed inside the engine pressure regulating system, it acts as the fixed supporting base for pressure control valves, ensuring accurate valve fitting and stable pressure adjustment. This valve seat effectively solves common faults such as unstable oil pressure, pressure fluctuation, valve jitter and internal leakage caused by worn, deformed or uneven valve seats, maintaining consistent hydraulic pressure and reliable operating state of the engine lubrication and fuel system.
Core Product Advantages
1. High-Hardness Precision Machining: Made of high-strength alloy material with fine grinding treatment, smooth and flat seating surface, perfectly fits pressure valve assembly, effectively eliminates assembly gaps and pressure deviation.
2. Excellent Wear & Fatigue Resistance: Special surface hardening process resists long-term valve friction and hydraulic impact, no groove wear or deformation after long-hour cyclic operation, greatly prolongs service life.
3. Stable Pressure Control Performance: Standard structural flatness ensures accurate valve closing and opening stroke, stabilizes engine oil pressure output, avoids power drop and unstable fuel supply caused by pressure disorder.
4. Anti-Corrosion & Anti-Oxidation: Premium surface treatment resists erosion of high-temperature engine oil, fuel and oil vapor, adapts harsh high-temperature and high-pressure working environment inside engine compartment.
5. Mini Compact & Precise Size: Compact dimension 3cm*3cm*1cm and lightweight 0.021KG, perfectly adapts to narrow internal installation space of Cummins M11 series engines without assembly interference.
6. Perfect Compatibility: Strictly standardized mounting size and structural radian, fully matches Cummins M11, ISM11, QSM11 engine pressure regulating system, supports plug-and-play direct replacement without modification.
7. Strict Factory Quality Control: Finished products pass flatness detection, pressure endurance test and wear cycle test, with stable batch quality for engine overhaul replacement and fleet bulk procurement.
