The Denison Hydraulics ZRE-AB-01-D1 (Part Number: 098-91020-0) is a premium modular pilot-operated pressure reducing valve designed for demanding industrial hydraulic systems. As part of the highly regarded ZRE series, this sandwich-style valve is engineered to precisely regulate and maintain a reduced pressure in a specific branch of a hydraulic circuit, regardless of pressure fluctuations in the primary system. Featuring a standard port configuration (P, T, A, and B), it seamlessly integrates into stacked manifold assemblies. Its robust construction ensures long-lasting durability, optimal fluid control, and reliable protection for sensitive downstream hydraulic components.
