The housing coded K 87086 is the robust external casing of the pressure regulating valve used in the ZV40/48 diesel engine’s fuel or air systems. Designed to endure high pressures and fluctuating temperatures, it provides the structural base that contains internal components like springs, seals, and actuators. Made from precision-machined, corrosion-resistant materials, this housing ensures the valve operates safely and efficiently, while withstanding constant vibration and fluid dynamics. Its critical role is to maintain system stability by securely housing the mechanism that regulates pressure levels essential for optimal engine performance.
