PVDB-LAN: Optimized for low-pressure hydraulic circuits, this model offers fast response times and reliable pressure limiting, making it perfect for light-duty industrial equipment and auxiliary hydraulic systems.
PVDB-KBN: Equipped with a robust balanced piston design, it excels in medium-pressure applications, minimizing pressure fluctuations during load changes—ideal for construction machinery, material handling equipment, and agricultural tools.
PVHB-CQN: Built for high-pressure environments up to 5000 psi (345 bar), this variant delivers rugged durability for heavy industrial hydraulic presses, mining equipment, and wellhead control systems.
PVJB-LQN: Engineered for precision-focused low-to-medium pressure systems, it boasts enhanced pressure stability, suitable for automated production lines, CNC machines, and precision hydraulic tools.
PVFB-CQN: Features a corrosion-resistant alloy construction and externally drained pilot configuration, eliminating backpressure interference to ensure stable operation in harsh marine, offshore, and saltwater environments.
